So, the only option I have is to take AP Calc AB. Does anyone know of any good books/resources I could use to self-study BC so I can take the exam. I really wanted to take BC so I’m kind of bummed.
I am not the expert on test prep books, but I’ve heard a few food things about Barron’s. I personally hated Kaplan’s calculus tests - they were full of errors or poorly written questions, to the point that they are nearly unforgivably bad.
If you are more advanced and want to challenge yourself, you can also look at AoPS’s Calculus textbook.
@MITer94 I heard of one book that was really good. Maybe it was Barron’s? Are you familiar with AoPS’s Calculus textbook? Any in depth thoughts? I have great grades in math, however I wouldn’t say it is my best subject. Although I do love a good challenge and being an independent learner! Maybe I will give the AoPs and Barron’s books a shot.
I didn’t use AoPS Calculus, but I’ve read the excerpts, and I’ve used other AoPS textbooks before. They generally focus on including a wide variety of interesting and challenging problems (some of them proof-based) and reducing the number of boring, rote exercises.
Do you think that would be useful for someone who is self-teaching themselves? I guess I’m just worried that I will not grasp the concepts enough for the exam.
Maybe. But you should have a firm grasp of AB (which I presume you’re taking) before self-studying BC.
No 
See that’s the issue. I have to take AB next year (as a senior). I was hoping there was a way I could just self-study the topics that are not covered with AB.
Ah I see. I’d imagine self-studying certain BC topics (e.g. integration using trig substitution, or the integral test for convergence/divergence of a series) would be difficult if you haven’t familiarized yourself with the AB material.
