Get a textbook at your college or local library (online versions might also be floating around). Read a chapter every 1-2 weeks corresponding to the AAMC outline and more importantly TAKE NOTES - in these notes, write everything you remember without looking back IN YOUR OWN WORDS and then fill back on whatever you missed out. The most important thing from my experience (I'm not self-taught btw!) is to build a true intuition via two ways: 1) Equations and 2) Explanations. UNDERSTAND how an equation is derived. Then understand why it makes sense = explanations. Try to relate them to your own life/experiences - this is harder to do for electromagnetics, but in that case imagine yourself as a charge, current, etc. in an electric/magnetic field and so on. Of course this is idealistic, so at the minimum have succinct but well-explained notes for each chapter.
Once read, refresh everything by watching corresponding Khan academy video (use his actual physics series; MCAT ones are not that good). Then do TBR passages for that section.
Also, how much do you need to study for the other sciences? If you are on a summer break and have done prereqs for the other 3 subjects, do this: in the next 2 weeks, don't touch the physics at all; spend it reviewing everything for bio, GC, and OC using TPR (TPR is the MCAT Goldilocks - not too detailed but still 110% of details needed for MCAT) or TBR with some daily passage practice. That way, during the school year you only need to learn physics on the side and can simply do practice questions for the other 3 subjects along the way.
