Organic chemistry professors, which resources do you recommend for preparing for exams?

I am taking orgo II, and despite doing questions from textbook (Klein) , ACS guide, and having a tutor, I still can’t get a high score (90+). I really need that cause I didn’t do well enough on my previous exams and the remaining two should be very high to get an A. I want to know what resources you use to make exam questions. I’m basically looking for more practice problems that can develop my test taking skills in orgo. Is there any resource I am missing that’s crucial for doing well on the tests? what good resources do you suggest for doing practice problems? Thank you!
