Shamim's Guide to Medical School Using Anki (USMLE Step 1 and Class)
This dude has a good system I hope to follow. He has you create 2 decks. One called Current Review and the other called Combined Review. When you are in a specific block, like MSK, you move all the cards from the MSK decks to the Current review. Once that block is done and move onto, lets say, respiratory, you'd move the MSK cards into the Combined Review and then move all the Resp cards to Current Review. After the resp block you move the resp cards into combined review with the MSK cards.
The idea being that you're combined review will continually grow with all your past blocks. With this set up he has it set to review AT LEAST 50 cards from the Current Review (at least) and then 50 of the combined review everyday so that youre getting random variety of your past blocks and retaining the info, while also heavily reviewing your current block cards.
I haven't started but this seems like a good set up that I'm gonna try.
