Absolutely, once you learn how to take the test, the rest becomes easy. I'm not the strongest test taker, and my practical knowledge exceeds my test-taking ability. That said, my knowledge base is also not as complete as I would like, and some of the facts I pick up in these review courses and practice questions are useful, and that's the true value proposition for me.

I will say that for the initial exams (i.e. the pre-licensing ones), the questions were terrible! They did not reflect practice at all. I recognized this from nearly the beginning. However, I find the questions for the specialty exam to be better and somewhat more reflective of our practice (even if not always applicable due to various logistics). I actually feel these are more useful, and thus I don't find them a complete waste of time - just tiring, haha.
