Taking six AP classes senior year?

Is it overly ambitious to take six AP classes senior year? I'm planning on taking AP Biology, AP Chemistry, AP Physics (B), AP English Lit, AP Calculus AB, and AP Calculus BC. I hope to attend Rice University.

It's not a good idea to take this many difficult AP classes your senior year. You will end up with an overwhelming amount of classwork while also dealing with college applications and (potentially) standardized tests. Colleges won't even see your grades in these classes until after you're admitted, so it's not worth it to spread yourself so thin. Rice will not expect you to take six AP classes your senior year. Six APs total might be a more reasonable goal. I'd recommend that you scale it back to three or four senior year APs.
