You’ve probably seen them or know of them: students who seem to breeze through classes and quizzes. They’re often the ones who prepared enough ahead of time to be able to ask questions in class. Sometimes they’re the ones who review after a class. The gist is that having some familiarity with a subject improves your likelihood of doing well in a course. Smart students know this, whether consciously or not.

Writing well is important to the success of college students, and the benefits carry over into your career. It never hurts to practice, especially most American college degrees have some sort of English course requirement for graduation. Good writing skills will always be of value to you in any career. The Tennessee Board of Regents has a prep course, Preparing for the AP* English Language and Composition Exam. To supplement this, consider taking another composition course, such as, First-Year Composition, or one of the many other grammar and writing courses available for free online, especially from Coursera.org and edX.org.

### Chemistry

#### #4. Preparing for the AP* Chemistry Exam

(source)

Chemical reactions are a daily part of our life. Many of the most basic things we do daily involve chemical reactions, from brushing our teeth in the morning to cooking a meal. Chemistry is known as a “central science” because aspects of it carry over into other sciences. If you are interested in a career in chemistry – or even just curious – the Cooper Union for the Advancement of Science and Art / Cooper Union offers a two-course series for students looking to take the AP Chemistry exam.

- Preparing for the AP* Chemistry Exam – Part 1 – Topics include the building blocks of matter, particle organization and structure, chemical reactions and more.
- Preparing for the AP* Chemistry Exam – Part 2 – Topics include atomic theory, periodic table, bonding and molecular structure, kinetics and more.

### Physics

#### #5. Preparing for the AP Physics 2 Exam

(source)

While chemistry is a “central science,” physics is sometimes referred to as a “fundamental science.” The laws of physics affect everything in the universe. If you’re interested in the many applications of physics, Rice University / RiceX offers a four-course series for the AP Physics exam:

- Part 1: Fluids and Thermodynamics – Topics include fluid mechanics, thermodynamic processes, systems and interactions, systems and conversation laws.
- Part 2: Electricity and Magnetism – Topics include electricity, magnetism, electromagnetic induction, space fields and interactions, forces and system changes.

If you want a less intense option, there is a single-course option, On-Ramp to AP* Physics C: Mechanics, from Weston High School.

### Mathematics and Statistics

While there may be a widespread fear of mathematics, it is an immensely important subject that factors into everything. Galileo, the famed Italian physicist/ mathematician/ astronomer/ philosopher and a “father of modern science,” even said something to the effect that the language of the universe is mathematics. Fortunately, as with any subject, familiarizing yourself with mathematical concepts ahead of time gives your mind time to absorb them for later review. There are many free math MOOCs available to give you a preview opportunity, and even extra credit if you write the relevant AP Exams. We’ve selected several courses covering calculus, statistics, and related topics.

#### #6. Calculus

(source)

Depending on how comfortable you are with calculus concepts, you have many choices of courses. A few worth considering are Pre-University Calculus from Delft University of Technology / DelftX, the three-course Calculus 1A-1C series from Massachusetts Institute of Technology (MIT) / MITx, or the four-course Single Variable Calculus series from The University of Pennsylvania / Coursera.

### Computer Science

Here’s a fact: there is a shortage of skilled software engineers in the United States, maybe even worldwide. Unfortunately, many people automatically lump computer science in with mathematics, and while math is a relevant skill, there’s far more to the spectrum of opportunities in this field, including visual design, interface design, psychology in terms of game theory and expected human behavior, and more. So it is not all about math and programming. But first, you need to know some of the basics.

#### #8. Computer Exam Prep
