How bad is not taking an exam?

<p>My AP comp sci AB class sucks, as my teachers lazy and taught us nothing for the entire year. How bad would it be if I didnt take the exam and have a score for it (i only got a 3 in comp sci A, same teacher and I self studied most of it). If I did I would probably get a 1</p>

<p>My other scores should be very good, as I should get AP National Scholar (8 4s or 5s) after these AP tests my junior year. However, I actually learn stuff in all of those class...but not in comp sci (im taking 6 this year not including comp sci)</p>

<p>Im thinking about applying to top colleges like MIT and Caltech. Will this drastically hurt my chances. I also do have a ton of national awards that MIT and Caltech likes, but I think it would look a little weird if I sucked at comp sci but am really good at math.</p>
