Online AP Courses

I was wondering if I should take an online AP Course over the summer or next school year I’ll be in 11th grade. I don’t know if they are worth it, or look good on college applications

You should take the courses that are appropriate for your academic level and not just for college applications. In terms of taking an AP course in the summer, keep in mind that the exams are only offered in May. Also, you need to find a testing site. Schools are not required to give homeschoolers access for taking the exams. Some schools are welcoming; some are not. I would contact schools in the fall about access. Typically by Jan you need to have secured a testing site. You will have to pay the school for the exam.
