<p>I will be taking math 2 in december this year but unfortunately there are a number of concepts that are foreign to me. Does anyone know any sources where I can get a breakdown of every concept tested? Or will Khan academy's course in pre-calculus suffice? I have Barron's math 2 book but I'd like to get more in depth with everything as I've never taken pre-calculus or anything similair in high school.</p>
<p>Just an fyi, I know all concepts tested on the regular sat as well as those tested on math 1.</p>
