How many practice AP exams should I take?

I have never taking an AP exam and I hope to receive a 5 on all my exams next year. I bought a few prep books but they only have 2 practice exams. Should I get more books or is that enough?

IMO, it’s fine. For all my AP exams, I took between 0 and 1 practice exams. You’re better off looking at old FRQ’s from the CB website.

Thanks!
