APES, AP Gov, AP Human prep books?

Is using crash course books for these exams enough to land someone a 4 on these tests?

BUMPPPP please I need to know!

I believe so. They are considered easier AP classes.

Princeton Review is the best for AP Gov

Do not use Barron’s for comparative gov, I got the book and it was a huge mistake. Not thorough at all. Princeton is great for AP US GOV tho, I love it.
