My instructor, Ben Smith, was pretty good. I went into the class with a fairly high score, hoping that I could snatch those 2-3 points that would get me the perfect 36 on the ACT. I think the main problem was that we spent a lot of time that got wasted going over tests and homework because half of the time we weren't even doing the problem I had missed. I ended up gaining 1 point, though I thought it was going to do more. The books and practice tests are definitely the most helpful part of the course. I just wish my instructor had gone through strategies and math content and had been more indepth with it.
