im a rising freshman, and im doing AP Precalc next year (alongside AP Human Geography) - what do I need to do?

Hi! I'm moving to a new school this fall, and it's a significantly better school than my middle school. All freshmen are expected to do Human Geography, but if your math placement tests are in the top percentiles, and you have transcripts showing you've done the relevant work, then you have to precalc as well (oops).

I know it's a step up from Algebra 1 and Honours Geometry, but i really love math and have been on an accelerated track for it since elementary school.

are there any resources that you can recommend so I can do as well as possible? I think it's crazy to expect a 9th grade to do two APs because it has the potential of wrecking my GPA before I've even really started, and I want to go to MIT. I'd rather just do Precalc and not human geog but that is NOT an option apparently.

any advice is really appreciated.
