<p>I read an earlier thread where someone advised against taking Math 20A. I also qualify for Math 20A and have only taken up to Precalculus in high school. I did pretty well for precal, and my major is Computer Science: Game Design. I want to take Math 20A, but it wouldn't hurt to make sure I won't get destroyed on my first quarter. Can anyone describe how hard Math 20A really is?</p>
