Does failing AP tests affect college admission chances?

My teacher keeps telling us that if we take all of the these AP classes but don’t pass the test then it’ll reflect badly on our transcripts since it shows we only took the classes for a GPA boost.

I honestly don’t think colleges care that much and that he’s full of shit so is this true???

I’ve taken 2 AP classes already and passed one of them with a 3 and I’m taking 2 more this year. My life has turned for the worse so I already opted out of taking one AP test (his test) but I’m being forced to take the other one that I know I won’t pass since I have no time to study.
