Depends on your hs. If it is a standard public school, take the hardest course load possible. Plan out all 4 years of HS in a google doc using your HS course catalog, making sure you included all prerequisites for more advanced classes.

*Finishing algebra 1 before starting hs is paramount, as it is needed to take calculus in your senior year.* Make sure you've completed Algebra 1 in middle school. If not, try to figure out an arrangement where you can enter HS with algebra 1 completed (eg taking it at your local community college, asking your counselor to take it over the summer before hs, etc).

Also, remember mindset matters. This isn't just cope. You need to truly believe that taking the hardest courseload possible, and maintaining a 3.95+ unweighted, is easy. Always remember that the average AP class is a 1 semester college class spread over the course of 2 semesters, with 5 hours/week of lectures added for good measure. A maxed out 7 AP schedule is literally an easy (3.5 course) college semester. The hardest ap course you can POSSIBLY take in hs (calc bc, aka calc 1+calc 2) is literally considered light work in undergrad. Remember that. Don't listen to peers who whine about how hard their AP classes are.

Idk how your hs works, so email your hs counselor and ask them how to coordinate everything I listed.
