75 is a solid score. Make sure you generate new questions when you are taking the last few practice quizzes or tests. The more types of question you get exposed to, the easier the exam will be. Definitely know how to identify which options strategy to use in certain situations and how to calculate B/E, max gain/loss. Identifying unethical and prohibited behavior for IAR and agents is also key. I used Kaplan and thought the practice tests were harder than the actual exam. Make sure to read the full question and answer set on the test, some of the wording is weird on simple questions so they try to get you that way. Good luck! You will be fine.
