Hi Mike, is it importat to read F3 books before starting F7? I have an exemption for F3, but I am not very familiar with theory of F7. However I have some practical experience. Is it enough to read only F7 in order to pass F7? What is your opinion of the best combination for F5? I want to take F5 and F7 or F5 and F9. I really like F5 and want to take another exam, with at least 1 day rest. Thanks
