1. Go through FA and concentrate on your weak subjects.
3. ANKI (if flashcards work for you then download this program and make yourself a deck of cards or download a deck for step 1; works great for topics that require strict memorization - biochem/micro/pharm/patho(disease names/mechanisms/markers)
4. Repeat repeat repeat , if you don't understand something in FA then watch videos or supplement with another resource but don't use more than that (example: BRS Physiology for weak topics)
Study for a solid month or so and then take another self assessment.
