I want to learn precalculus before the school starts, but just for fun. What are some low priced summer school courses (where you can go at your own pace) that are high quality?
Khan Academy- it’s free and very useful. I’m taking pre-calculus/trigonometry next year and will be using it to review some stuff that I missed and also to maybe learn a little bit of pre-cal although my main goal is to strengthen my foundation.
@Cannkat I’m doing a free course through ASU. I’ll see how that goes. Kahn’s practice is nice, though I don’t like their videos.
