<p>@ham,</p>
<p>After I was admitted last year, I decided not to take any of the APs that wouldn’t get me credit (aka chem, bio and comp sci) in order to save money. So in your case, that would mean not taking physics B (the alternative would be to self-study and take the physics C exam if you feel up to it, as a 5 on both sections would place you out of 8.01). When I made the decision not to take some of the exams listed on my application I emailed MIT and they said it wasn’t a problem, so don’t worry about that.</p>
