I'm going to give my perspective on using it for undergrad since I'm not yet a med student. First off, you need to understand everything that you put into anki IN CONTEXT before you put it in. Anki just helps you retain the info so instead of cramming the weekend before an exam to re-learn everything, you still remember it all from lectures. As far as how you put content in, that's up to the individual. For simple memorization like learning amino acids, it's straightforward. For more complex stuff, it needs to be catered to the individual and to the course. Sometimes I prefer cloze style cards where you essentially turn all of your notes into cards with omitted words (cards should always invoke active recall). Other times I will use lots of diagrams. I've even had times when I got lazy with making cards and would literally just write "draw out X pathway" or "describe Y process" and then include where I can find the answer in my notes/book. That way anki would literally just act as a study scheduler and it still worked well. The key is to make everything active recall and stick to the review schedule.
