<p>I got a 5 on the calculus AB AP exam my JUNIOR year. Since my school didnt offer Calculus BC, i didnt do any calculus at all my entire senior year. Now im at berkeley, and ive decided to retake Math 1A since ive basically forgotten a lot of the stuff ive learned since i havent touched calculus in 1 year+.</p>
<p>but now im worried. people say math 1b during second semester is killer. should i just brush up on calculus and immediately start with math 1b instead of going back and 'retaking' math 1a?</p>
<p>either way is bad. if i start with math 1a as i am doing right now, i will have to confront the infamous math 1b during second semester.</p>
<p>if i take math 1b right now, it wont be as bad as during second semester (when all the premeds get there) but i will also not be entirely prepared (as my calculus is rusty).</p>
<p>I agree with vicissitudes, Math 1B is a pretty hard class, and if you never took BC it would be tough. I would relax in 1A, you don't always have to take the toughest classes.</p>
