My son is in third semester calculus, which is multi-variable. Several of his friends already took it, but none tested out of it that I know of. He had a 5 on his AP Calc BC exam, and we talked about what class he should take.
When it came down to it, if he used all his APs, he would have more than a semester’s worth of credits “transferring in”. So now he has a semester available to do a co-op without worrying, or maybe a semester abroad.
I cannot imagine, for the life of me, and knowing the material on the AP Calculus BC exam pretty thoroughly, that it would be productive for a student who got a 5 in May on the exam to go back to square one “what is a derivative?” and “what is an integral?”.
It is more productive to move on and spend time on other things.
Thus, the major benefits I see for “skipping” all you can are:
- graduating early if you want (if your college allows that and both allows you to skip and get credit, like my son’s college does)
- doing a co-op for a semester without worrying about graduating late
- doing a semester abroad, again without worrying about graduating late
- not being bored in material that is old hat for you
And one other secret - YOU CAN CHANGE CLASSES!!!
If, let’s say, someone took AP Calc BC junior year, got a 5, and took no math senior year, and signed up for Calc 3, and they got to class and were blown away, they could switch to Calc 1 or Calc 2. This would be within the first week though, if you don’t want to miss much.
And finally - again, if the college allows credit as well as skipping - if the student has more than a full semester of AP credit, mom and dad save 50% of yearly college costs. We save 20K, and my son’s loan total is less than twice that. Nice to have a cushion to help him out if we need to.
