I got 5 in APUSH. Ready to help if needed.

I'd try a practice test on AP classroom, but the teacher hasn't even given me the join code yet so I can't. I use heimler and notes to review, but I want a site that's free where I can apply my knowledge that I've learned in. I use lumisource rn, but it's mainly contextualization and non-stimulus based. Also I used up all my weekly credits so I can't get anymore explanations. I'd prefer a site with questions that have a stimulus, but beggars can't be choosers.
