AP Art History: DO or DON'T?

I am currently a junior in high school, and I am thinking about taking AP Art History online. I am only taking it because I need it as a GPA booster and want to learn more about the arts. However, I know I am not going to take the AP exam for the course. If you have taken AP Art History online, could you tell me whether it was easy or not? A lot of work? Do you recommend it?
