It feels a bit like maybe you’re trying to make up for lost time with APS. You took AP Euro in a previous year and are currently taking 4 more APS at school this year as a junior, which would give you five total. Is that why you are also self-studying 3 more - so you can have 8 AP tests on your applications? Or are you self-studying those because your school doesn’t offer them and you want/feel you need them? Taking four is already a lot in one year; seven seems like too many.
A frequent comment I see here on CC (and that I think DramaMama2021 was hinting at) is that schools do not count self-studied APs as equivalent to taking AP classes when looking at your application. They may give you college credit if you get a good score, but that only happens if you’re accepted. Somebody else here can probably explain it better. I may not have that quite right.
