I'm just starting to study and this is how I'm doing it.
1. General Principles - Behavior Sci, Micro/Immuno, Biochem/Genetics, Pharm (Kinetics and Dynamics), General Path
2. Organ System - CVS, Endo, CNS, Heme/Onco, Renal, Resp, MS, GIT, Repro
(each OS done in this format - Histology → Embryology → Anatomy → Physiology → Pathology → Pharmacology → First Aid to summarize)
This is the breakdown I would like to adhere to for GP
Behavior Science (3days) → Micro (4days) → Immuno (4days) → Biochem (5days) → Genetics (3days), General Pharm (1day), General Path (5days)
I'm not sure how long OS will take, but I can't imagine more than 2 weeks.
After which I'll take an NBME, make note of my weakpoints and start Uworld while annotating FA.
Then it's just about going over FA as many times as possible while doing questions every day. NBME's periodically and take care to go over weaker points until they're not weak anymore.
A lot easier said than done, however. Hope this helps.
