<p>Math II is really, really easy to get an 800 in with adequate preparation, and so is the AP exam very easy to get a 5 in for even those who’re terrible at math, to be honest. I’d focus on actually learning calculus well, because that’s very, very important if you’re going to be an engineer. Ditto on IMS’s advice regarding doing well on the BC exam. Be sure to get yourself to the point of getting a 5 with zero effort on the BC.</p>
