I used Anki in Anatomy, and was the most abysmal student of my class. But I know some people swear by it, so there you have it.
I think it's one of those things that works for some and fails other people. IMO any flash card system takes some finesse to pull off successfully, because you need to strike the balance between dumping walls of text on your card (and thus defeating the purpose of the exercise) and putting too little on there (and thus excluding some high yield information).
Personally, I like to make lecture outlines. However, when I first watch the lecture (on 2x), I take no notes because I want to focus on what the lecturer is saying (and I find that focusing on your notes makes you focus on the slides rather than the lecturer's words). I'll usually watch some of the lecture again (on 2x) when I make an outline. Then I'll review those outlines later.
Of course, I'm not a great student, so you probably won't take my advice, but I thought I would share it, because it turned me from a failing student into an average-ish one. If you were a solid student already, it might make you AOA material!
