Self-Study for APs worth it?

As of right now, I’m on track to graduate with 7 AP classes… Should I self study for more? I my school doesn’t offer an AP class for a subject, should I take honors and then give the test a shot?

Also… AP statistics VS AP Psychology?

There’s no reason to self-study unless you want college credit for a class your school doesn’t offer or that doesn’t fit in your schedule. If your school offers a given AP class, colleges want you take the class and the test rather than just the test. If your school doesn’t offer it, colleges don’t expect you to take it, and you’d be better off working on your ECs or studying for the SAT or something.
