i have been studying for it a while and i put effort in, but i'm really stressed because i still find learning it difficult especially since i'm self-studying it. what do i do if i fail the test?
Take it! If you fail you do not have to report it on the Common/Coalition app.
Failing a test will not influence your college applications at all, because test scores are not included in your applications. Once you send your college your score report when you are registering for classes, they just won't give you credit for the exam you failed. They won't care that you failed it though, and it's not like they would take back your acceptance.
So if you already paid for it, there's no reason not to take it. However, you should also consider the reasons why you are taking AP exams in the first place without taking the classes and make sure you have a plan.
