What is it Like to Attend Duke University

What is it Like to Attend Duke University The tutors behind Varsity Tutors are not just here to teach theyre sharing their college experiences as well. Margaret is a Washington D.C. tutor specializing in Writing tutoring, AP Psychology tutoring, all levels of Spanish tutoring, and more. She is a graduate of Duke University holding a Bachelors degree in Psychology. Check out her review of her alma mater: VT: Describe the campus setting and transportation options.How urban or safe is the campus?Are there buses or do you need a car/bike? Margaret: For my undergraduate, we had an interesting situation. There wasnt that much public transportation at the time in Durham, North Carolina. I think that might have changed in the last decade. However, we always had a free bus service not only for the campus, but between our school and The University of North Carolina at Chapel Hill called the Robertson bus. It was a way to go to not only different library resources if we needed them, but to a different, more typical college town. Durhams not exactly the safest place as its very urban and not a place to walk alone at night, to be honest. Chapel Hill, by contrast, was the typical college hamlet and it was a fun place to be able to get to as a change of pace. VT: How available are the professors, academic advisers, and teaching assistants? Margaret: I really had a great relationship with my professors as I got to my upper level classes. They were great mentors as I worked on applying for graduate school and on my senior theses. That said, as a freshman, I had pretty terrible teaching assistants for General Chemistry who were barely able to speak English. It made the class almost impossible to pass and I resented it. VT: How would you describe the dorm life rooms, dining options, location, socialization opportunities with other students? Margaret: I always laugh about the dorm life. There was this show from the late 90s called Dawsons Creek that filmed its final two seasons sometimes on Dukes campus to show where Katie Holmes character went to college. Her dorm room was massive. I knew kids my freshman year whose living space was literally converted from an old janitors closetfor two people. Despite the price tag, you dont go to Duke for spacious on-campus accommodations! VT: Which majors/programs are best represented and supported?What did you study and why? Did the university do a good job supporting your particular area of study? Margaret: I know back in 2002, that the big thing to start majoring in was in Investment Banking. I know that since the bank crashes in 2008, thats probably not the hot ticket major it was before. Of course, Dukes extremely proud of its pre-med program and takes about 10% of its actual medical school classes from its undergraduate program, which is fairly unheard of. Also, theyre very supportive of their pre-law students and make sure they have the best resumes possible before applying to programs. I was a Psychology major and we had a great wealth of access to lab research and paper writing opportunities. I always felt supported there. Similarly, as one of the few people involved heavily in their primate/lemur studies program, I had very enthusiastic mentors who were happy I was continuing their work. VT: How easy or difficult was it for you to meet people and make friends as a freshman? Does Greek life play a significant role in the campus social life? Margaret: Its possible to make friends without Greek life. In fact, Duke wont let anyone rush a fraternity or sorority until the second semester so bonds can be established before then. That said, I made great sorority friends when I did rush and join but I also had great friends whose weddings Ive attended since then that I met the first week in my freshmen-only dorm! VT: How helpful is the Career Centerand other student support services?Do many reputable companies recruit on campus? Margaret: I honestly dont know. I never used it because I was in a science track and relied on my mentors to help me apply to graduate schools. VT: How are the various study areas such aslibraries, the student union, and dorm lounges? Are they over-crowded, easily available, spacious? Margaret: Again, this is sort of a sign of having been out of college for so long. When I was there, the main library was Perkins and hadnt been renovated since the 1970s. However, by the time I was a senior, most of the library stock had moved to a beautiful, new spacious library called Bostock. I lived in Durham again for two years from 2011-2013 for other reasons and sometimes went into Bostock for books and research. Its not overcrowded, has comfortable sitting areas, and tons of available computers. So, Dukes come a long way from when I was using their stacks. VT: Describe the surrounding town. What kinds of outside establishments / things to do are there that make it fun, boring, or somewhere in between?To what extent do students go to the downtown area of the city versus staying near campus? Margaret: Its Durham, North Carolina. Theres just not that much to do. I like the South Point Mall off campus. I also liked going to Chapel Hill. Again, take the free bus over there on weekends. Its your best bet! VT: How big or small is the student body? Were you generally pleased or displeased with the typical class sizes? Margaret: It was about 6,000 undergraduates back then with about 1,600 per class. The typical intro class sizes for things like General Chemistry are huge, but mostly, the classes are around 20 people. Its very intimate past the general requirements. VT: Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Margaret: I dont have one memory specifically as much as a whole year. I really enjoyed every minute of working on my senior thesis for lemur studies with my mentor, Dr. Digby. She had been my favorite teacher in the primate department and she was invaluable in helping me get grants and learn the art of being a good scientist and building up my own study from the ground up.

How to Talk about Transport in English - Intermediate Level English

How to Talk about Transport in English - Intermediate Level English Transport and the ways we use it in our daily lives captures the attention of all of us. I thought that today I would talk about transport in English and set out some of the means of transport we use in English vocabulary across Europe and the UK. This will help you to improve your English. Talk about Transport in English Transport to work is often a choice of Private or Public  transport. Private transport is what we provide ourselves (e.g a car) or by a private operator who wishes to make a profit. Public transport is the means of transport which is provided by governments and is not necessarily provided for profit.Vehicle  is a general noun used to describe any motorised method of travel and transport. This can include a car, bus, lorry and truck. The choice of vehicle depends normally on where we live. Governments usually provide many different choices in capital cities  and bigger towns  but there is normally less choice in rural  or country areas.Some examples of private transport are:cars saloon cars, sports cars and 4 x 4buses double decker, single decker, mini buses and trolley buses.For those who wish to skip the traffic then there are  motor bikes (motor cycles) and mopeds (scooters) are becoming increasingly popular.Taxis remain popular for those in the larger cities such as London and N ew York. You can find taxis waiting for passengers at a taxi rank. We now also have the new taxi option referred to as Uber Taxi’s.  Public transport comes in the following forms:buses double decker buses such as the traditional red buses seen on the streets of London and regular single decker busestrolley bus   buses with overhead power lineselectric bus this is a bus powered by electricity and they are getting very common in many cities in Europetram is a vehicle powered by electricity, it travels on 2 rails that are laid in a public roadcoach this is a bus that runs between towns and citiesTrains also come in many guises (forms) diesel, electric, underground and over ground). Trains travel on two tracks made of metal.Underground trains have different names depending on the city/country that we live in. In America they are referred to as subways, in London as simply the underground or the tube and other cities as metro. You wait for a train on a platform.If you prefer a fast way of travel, then you can use an aeroplane. Nowadays there are many budget airlines (companies that fly passengers by plane) and you can fly to many destinations relatively cheap.  If you are travelling to an island, you might prefer to take a ferry (a boat or ship that transports passengers and/or goods, especially over a relatively short distance and as a regular service). If you happen to travel overnight, then you sleep in a cabin.If you have travelled in Asia you will be familiar with the very small Tuk Tuk  a mix of a motor bike and small car. A great way to travel and sometimes the only means of transport in rural areas.And I am sure most of you are familiar with a bicycle, you pedal your bicycle and get from A to B easily. It is also a great exercise! Public Transport in English - Infographic Enjoyed this infographic? Here’s what you can do next:

Simple Reading Practice Tips to Boost Your Childs Reading Skills

Simple Reading Practice Tips to Boost Your Child's Reading Skills Have you ever wondered about methods of reading practice for kids that can boost your childs reading skills and academic success? Sometimes the challenges of a struggling reader can feel overwhelming and it is difficult to know where to start to help your child succeed. The good news is that boosting reading skills isnt impossible and you are fully equipped as a parent to help improve your childs learning with targeted reading opportunities that extend to all subject areas. Consider these helpful methods of reading practice for kids that support your struggling reader: Read every day You can never underestimate the power of simply reading to or with your child. The time spent in books is beneficial and magical and will help to unlockuntapped reading potential. Not only are you exposing your child to a world of reading you are modeling that reading is both useful and enjoyable. Think outside the book Reading practice shouldnt be limited to books. Thinkabout what your child enjoys most and find a variety of materials tosupport these interests. Consider magazines, manuals, brochures, or onlinereading. Using magnet letters or letter cards with emerging readers isalso a great way to practice reading without using books. Understand expectations As a parent it is important to stay up to date on current grade level expectations for your child. Knowing what the mastery standards are can help you gauge your childs progress. Comparing your childs skills to the grade level and developmental expectations will provide information on your childs strengths and areas of necessary growth. Utilize all possible resources If your child is struggling it is important to utilize every resource available to you. Investing in targeted reading tutoring can help your child gain the necessary skills for success and an online reading program can build skills while providing an interactive learning environment. Talk with your childs teacher about what is available and what would best match your childs ; needs. Boost vocabulary As children become better readers they are confronted with more complex topics, plots, and vocabulary. Understanding increasingly difficult vocabulary is vital for reading success. Teach your child to identify unfamiliar words and find ways to search for meaning. Encourage the use of context clues around the word or work as a team to look it up in a dictionary to find the meaning. Picture it Good readers, regardless of age, picture the story in their minds. These mind movies should play along as each word is read. Many struggling students fail to visualize the story and errantly miss important information. You can easily practice this strategy with your child by reading a passage aloud and then discussing the scenes you formed in your mind. If your child is unable to visualize the passage you can reread and prompt him with questions to elicit more information. Emphasize a books structure Every genre has a different layout and different text features to support the organization. For example, reference books utilize headings, subheadings, table of contents, glossaries and appendices while novels have chapters, dedications, and occasional illustrations. A child should understand the text features and how they work together for an intended purpose. This is especially beneficial to success in other subject areas that utilize content specific reading. Talk about books Reading with your child is important but talking with your child about books is just as powerful. Your child will benefit from viewing you as a reader and someone who learns from books. Take time each day to ask your children about what they are reading, discuss a library book you checked out as a family, or share something you learned from your own reading. These are just a few tips to help improve a childs reading ability. What are some other ways to engage in reading practice for kids?

6 Ways University is More Challenging than School

6 Ways University is More Challenging than School On the academic front, the move from school to university can be a challenging one, as there are significant differences. These differences include the level of study, long-term projects, working in groups and getting your work done. The Level of Study Although you learned a lot in school, every topic that you study in university will be more in-depth. The simple concepts learned in school evolve into complex ones and study is more advanced. Expect to have to put in more study time to attain a good grade. In addition, your professors are going to look for a higher level of analytical and critical thinking skills than many of your school teachers ever did. Long-Term Projects Many university courses entail long-term projects that require motivation, discipline and organisation. You'll have to start early, stay on task and organise the project. Keep in mind that a long-term project cannot be completed in a short period of time. And if you're not feeling especially motivated, you'll still have to dig deep to find some motivation. Working in Groups It's not uncommon for university students to have projects that are assigned to groups. This means that you will have to coordinate your time and effort with other students, even if you don't like some of the students in your assigned group. While university isn't exactly the real world yet, it's fairly close to it. School Teachers and University Professors Most school teachers try to keep students on track with their academic work. They offer extra help to students who are struggling. Often, they come to you. It's not like that in university. If you need extra help, you'll have to ask for it. And if you miss a test or need to do extra work for extra credit, those opportunities won't be available like they were in school. Note-Taking Challenges School teachers follow the subject textbooks very closely and write everything that should go into your notes on the whiteboard. In university, you'll be mostly taking notes on what is said during a classroom lecture and also on reading assignments that aren't talked about in class. Plus, much of what is tested may not even be in the book. School Tests and University Exams In university, tests are administered less frequently than school. College tests and exams cover more months of material. The exams are also more challenging. Not only will you be expected to demonstrate learned facts, but you'll be required to apply them to individual circumstances. For this reason, university tests are generally more stressful.

8 Cheap Alternatives To Your Favorite Technology Accessories

8 Cheap Alternatives To Your Favorite Technology Accessories Image via https://bizlaunchblogdotcom.files.wordpress.com The following eight technology accessories are cheaper and better alternatives to more popular brand name items. (I actually own most of these, so I can vouch for their usefulness and quality.) I recommend trying these little gadgets out, because they can make your life a whole lot more convenient without breaking the bank! 1.)  Portable Mini Speaker by Accessorize Your Life: $14.99 Image via Amazon.com This portable mini speaker is an improved (and often cheaper) alternative to similar accessories. I originally bought this speaker because my laptop’s sound volume is pretty poor, and this portable device was  exactly  what I needed. This speaker connects via audio socket (speaker/headphone jack) to your computer or MP3/4 player to deliver amazing, enhanced sound, and at only 3 ounces, it’s (like the advertisement says) “ultra-portable.” Unlike with some inferior speakers, you can also hook multiple Accessorize Your Life speakers together for a more intense sound, like for at that party where you need some banging bass. Even better, this mini speaker comes with a handy mesh carrying case and charging cord, so you have everything you need both to transport it and set it up right out of the bag. 2.)  Portable USB Car Charger by Volmate: $12.98 Image via Amazon.com We’ve all been there: you’re stuck in the car and your phone’s dying, and you wish you were home so you could just plug the darn thing in. Well, with the Volmate Portable USB Car Charger, you don’t have to worry about that anymore! This car charger plugs into your cigarette lighter socket and offers up three (count ‘em, THREE!) USB ports for you to plug all of your tech goodies into. Two of those ports are essentially to charge phones, while the remaining outlet puts out more charge so you can charge larger items like a tablet faster. However, since the Volmate creators have apparently thought of everything, their “smart charge” characteristic ensures that devices charge at only the maximum speed, and also automatically stop when the device battery is full. What more could you ask for? 3.)  External Battery Pack by PowerGen: $39.99 Image via Amazon.com This is by far the most expensive item on this list, but don’t let that deter you: the PowerGen External Battery Pack is worth the investment. Basically, you charge this item on your own time and then use it as a completely portable charger (no plugging into an outlet required!) for your phone, tablet, or other device when you don’t have access to a wall or car outlet. This external battery pack packs a punch, putting out 12,000 mAh (that’s milli Ampere hours, the units for how much energy a battery can store). What does that mean for you? Basically, that it can charge an iPhone about 5-6 times, an iPad Mini 1.5-2 times, an iPad 2 1.25 times, and an iPad 3 or 4 about 65 percent. For those of you who haven’t done research on such things, that’s pretty darn impressive for a technology accessory that’s only a little bigger and heavier than an iPhone 4. Finally, it has 3 USB ports to charge 3 items simultaneously, and it also has a built-in flashlight that’s extremely convenient. Frankly, you can’t go wrong with this device, and the best part is, PowerGen has a variety of charger sizes (with corresponding larger or smaller battery charges) available for all of your needs. 4.)  Dual USB Wall Charger by PowerGen: $13.99 Image via Amazon.com So, you might be wondering how you’re actually supposed to charge #3 on this list, no? Well, with the PowerGen Dual USB Wall Charger, that is! You simply plug a USB cord (that is, a cord that has USB adaptors on both ends) into the PowerGen External Battery Pack and into the PowerGen Dual USB Wall Charger, and you have instant charging. And that’s not all this wall charger can power. The PowerGen Dual USB Wall Charger simply plugs into a wall outlet and lets you charge any device that can be connected with a USB cord. That means phones, tablets and more. 5.)  4-in-1 USB Charging Cable by COTTEE: $8.99 Image via Amazon.com Now that you’ve been introduced to a few accessories, you’re probably worried about the number of charging cables you’ll have to carry just to deal with all of these new items. Well, never fear, because that’s where this 4-in-1 USB Charging Cable by COTTEE comes in! It’s basically one wire that splits into five adapter heads so you’ll never lack an adapter for charging all your devices. Aside from the USB adapter head, there’s one for the iPhone 4, Galaxy 5s/Note 3, iPhone 5/6, and a Micro-USB. Essentially, that’s everything you need for all of your Android and iPhone smartphones, in one convenient place. 6.)  International Travel Plug Adaptor Kit by Ceptics: $6.99 Image via Amazon.com Looking to study abroad sometime soon? Then this is the ideal accessory for you! The Ceptics International Travel Plug Adapter Kit is a nifty accessory that combines all of the outlet adapters you need for the “U.S., Europe, Asia, China, Australia, New Zealand, and the UK” in one handheld item. The outlet adapters all snap together into a configuration that’s small and protected, but also easy to take apart and use in a second. 7.)  Universal Travel Case for Small Electronics and Accessories by AmazonBasics: $10.49 Image via Amazon.com Now that you have all of these cool tech accessories, you need something to carry them in, right? Well, that’s where the AmazonBasics Universal Travel Case comes in. This sleek case boasts four different sized inner mesh pouches to strap in all the small electronics you could possibly have. In addition, the “molded EVA-plastic exterior” provides both the necessary protection for your delicate devices and a cool look. As a bonus, it comes with a removable wrist strap for convenient transportation. 8.)  Magnetic Mount Holder for Cell Phones and Mini Tablets by WizGear: $13.99 Image via Amazon.com This is the last item on this list, but definitely not the least. In fact, I think the WizGear Magnetic Mount Holder is actually one of the coolest items on this list. This tech accessory mounts onto your car’s dashboard and uses magnets (including one that you place between your phone case and phone) to hold your phone securely in your car. After all, nothing’s more important than car safety, and this gem prevents you from having to look down at your lap just because you have nowhere else to put your phone. And at $13.99, this steal is practically criminal.

Definition of Mass in Chemistry

Definition of Mass in ChemistryWhy is it important to know how to define mass in chemistry? Well, because there are different things that are related to it.For example, you may know that the mass of a substance is equal to the weight of that substance multiplied by the volume. But do you know why that is? That is because the mass of an object is determined by the amount of mass it has divided by the weight. So that is the reason why a person cannot measure or weigh a lot of different substances at once if you want to estimate the mass of a substance or idea that you may have.However, once you find the formula for this equation, you can use that in your equation to define the mass of the substance or idea. It is just like how a person can just say something like 'that object weighs 10 grams' and it would be correct. In this case, that would mean that the object weighed in the certain number of grams.Now, what if there were two objects that weighed in the same way, but one was heavier? Well, there would be something like this. The one that weighed more would be heavier and the one that weighed less would be lighter. The same thing applies to the mass of a substance, it would just mean that the mass is the number of grams multiplied by the volume.With this, you can now calculate or define the mass of a substance without having to determine its mass and also what quantity it contains. This is the main purpose of knowing how to define mass in chemistry. It is important in science because there are different elements and compounds that need to be measured to determine the mass of these things. But you cannot determine the mass by itself.In physics, mass is important when studying different types of forces. For example, if you look at a bottle of soda, you can see how the mass of the bottle is dependent on the density of the soda, which is in turn dependent on the size of the bottle.This equation is called the Dalton Equation and this term uses that equation in determ ining the mass of a substance or idea. Now, this equation can also be used in chemistry. You may already know how to use it in studying various metals and different substances, but once you find the formula, you can now use it in your equations to define the mass of a substance.
