AP classes are rigorous, college level courses taught in a year-long class to high school students. They tests can be taken by any high school student, even if you don't take an AP class. You read that right; you don't have to take an AP class to take the AP exam. The College Board® says, "The AP Program encourages schools to assist homeschooled students and students whose schools do not offer AP courses and exams."
AP Exams for Homeschooled Students 

Recent news articles highlight new ways of teaching with AP classes. Some teachers are using experiential, hands-on learning, instead of lectures, as they teach their AP classes. An independent homeschooler can provide the course content their child needs to learn the material, whether that means textbooks, projects, or anything else.

Some AP students study so much they have little free time, and get little sleep. A parents group and a university suggest that top students should cut back on the college-level classes. There are some homeschool students taking multiple AP exams who are so busy with those classes they can't even complete the core subjects outside of those classes. Some top students feel pressure to take up to three AP classes a year, but that can really back-fire and cause serious burnout. Instead, teach your child in a way that preserves their love of learning, while keeping them college-ready and challenged.
