Guidelines for the comprehension of the tests are required in each test. The instructions are also essential to progress. If you have proper guidance not only in the F3 but even in every examination, you can easily solve it, whereas if you don't have guidance in your area, you don't know what to do even though you have the best books for your course, you can't take advantage of these books. They're always worthless to you. If you have the right Guideline for F3 you can pass this from only your notes. Set a Guideline for you to excel in your course and this Guideline changes time as needed for CIMA exams.
