Prep for Math 1201 College Algebra

Hello all,

It's been over a decade since I took a math class. I finished high school already behind the curve, so I'm jumping back into a point I didn't quite reach before I graduated.

I have 3 weeks left before the final exam, and I am looking for the most efficient guide on what to work through on Kahn Academy. The class has been all about functions: linear, quadratic, polynomial etc. We are just getting into logarithmic stuff which is completely foreign to me. Help!
