AP Biology review book help!

I’m currently taking AP bio and looking for good review books for the AP exam. I currently have the Princeton review, but it’s questions aren’t so similar to the test ones. I hear Sterling AP bio is good, but are their questions the same type as the exam?
Also is the cliff notes a better book?

Barrons AP BIO Prep although usually tougher than the AP exam will prepare you thoroughly if you study it properly. Then the real exam will be really simple.
