More AP's Junior year than Senior year?

Does it look bad to colleges if from having taken more AP’s Junior year, you take less Senior year?

As long as you’re challenging yourself I don’t think it matters too much. Unless you’re going from a huge number of APs to a few (Ex. 6 APs to 2).
It also depends on how many APs your school offers and the practicality of taking each class. If you go from having 5 easier APs to 3 more difficult AP classes then it shouldn’t really matter.

No, as longs as your schedule is still challenging.
