@julia99 “My high school has rigorous AP courses… I’m not sure how many I should take.”
Generally, it is better to take fewer AP courses that are more central and do well in them. Generally the one that are the most beneficial are AP Lang, AP Calc (preferably BC), AP Physics C, AP Chem, AP Bio. Try to add PE and study hall to limit your course load. Then really work hard on these. Try to get an A or B and at least a 3 on the exam, but a 4 or 5 is better.
I would avoid AP Euro, unless you love the subject, because it is not central and it is a time eater.
