AP Testing Suggestions

Hello. I would love some feedback on AP tests to take after the class or self-study (if any) this coming year (my junior year) and next year (my senior year).

I took no APs freshman year and one AP last year. I received a 4 on the European History test. Not to make excuses (although I totally am), I didn’t study and had a cousin pass away a few weeks beforehand.

This year I am enrolled in:
AP US History
AP Calculus AB
AP Physics 1

I want to also self-study for AP Physics C: Mechanics exam because I’m confident in both physics and calculus. Any recommendations for review books or online lectures would be greatly appreciated. Also, I would love to hear any solid objections about doing this as well.

I’m completely lost for my senior year. I will definitely be enrolled in AP Government, but everything else is shaky at this point. I am taking the two-year IB English course, but my safety school does not take that test for credit. I will opt to take one or both of the AP English tests. Any thoughts to which one or even both? I know very little about the AP English curriculum.

Other classes I am considering for my senior year:
AP Computer Science
AP Psychology
AP Biology
AP Chemistry
AP Calculus BC
AP Statistics
AP French

I have no idea, which of these classes I’d prefer to take. I’m interested in all of them. Any recommendations on which to take, not take, or self-study?

Unfortunately, my school does not offer AP Macroeconomics or Microeconomics. Is it feasible to self-study either of those? I find finance and economics fascinating.

Something I didn’t mention: my school is actually an IB school. However, it has become impossible for me to be a full diploma candidate due to scheduling conflicts with Theory of Knowledge. Consequently, I have made the decision to save money and focus on AP testing. Because of this I will be taking IB Biology and/or IB Chemistry classes, but will be taking the AP tests. Is this a terrible idea? It will most likely require more self-studying to become acquainted with the AP curriculum.

Sorry for all the details, but I would be grateful for any feedback.
