AP Classes in senior year

So my school weights AP classes on a 5.0 scale in your gpa. However, they don’'t count your senior year gpa in your cumulative gpa that gets sent to college. During junior year i am taking 4 aps (AB/BC Calc, English Language, and Chemistry). So should i take 2 aps senior year ( ap bio and ap physics) or try to get college credit and take 4 (ap bio, ap physics, ap comp sci, ap stat)

I also heard that some colleges still make you retake the class even though you passed the ap test

Take 4, colleges will still see your senior year course load.

That is true. Check the prospective colleges AP charts.

The point of taking APs isn’t to get credit, but to have the most rigorous classes you can. At top schools, it’s often the “expected” preparation and most freshman classes are “post Ap” in level. So, if you intend to go to a top 25 private university/LAC, expect not to get credit.
Is it possible for you to take AP bio, AP physics, and either AP Comp Sci or AP Stats? AP stats is one of the easiests APs so you may take it, but it depends what the rest of your schedule looks like (remember that top schools will expect 4 years each of English, Math, Foreign Language, Science, and Social Science).
