Okay as a fellow rising senior, here’s what I would do. I would just not sent that one AP Bio score if you get a 1 or a 2. However, I’m pretty sure this costs money. So if you can afford it do that. But, if you have a reason why you got a 1 or a 2, then you should probably explain it to the college, I think they can be forgiving. If you get a 3, then I think you should send it either way, because if that’s the only one that has a three then it could be seen as a fluke.
But also, I’m pretty sure some colleges require that you send all scores no matter what. Like I’m pretty sure Yale does this, so there’s no hiding from them. If you’ve taken all your other exams for your other AP classes this might look suspicious though. So I would just be careful. Hide the score from the colleges you can. But if you have an excuse, explain yourself in the application.
If you can talk to your guidance councilor about this.
Good luck.
