• Khan academy is wonderful. I recommend it to students all the time, and I use it myself when I need a refresher on some topic that I learnt years ago and have forgotten since.

    Also of note, if you are interested in a more structured course on a topic rather than individual lessons, is EdX which offers a variety of free online introductory and intermediate college courses from a number of excellent universities (like MIT, Michigan, Harvard, and Wellesley to name a few).

  • Shall we make this the general Introductions post, then?

    I can help with English grammar, academic writing, and Math through pre-calculus. I am also happy to help with standardized test preparation (specifically ACT, SAT, GRE, GMAT, or LSAT) as that is my actual profession!
