If you have a logical and tidy mind you'll find much to offend you in aviation. Much of it is a 'dogs breakfast' ! Anomalies and contradictions abound. Go with the flow. Study that which you need to pass your exams. Once you've passed, your time will be pre-occupied with gaining experience and becoming a better pilot.
Much of that with which you stuffed your mind, will never again be needed. Good luck.
