This is how I use Anki:

Skip through all of the fluff in his blog, and read the part about his Anki card system. I take screenshots of all of my lectures and make a question based off of those lectures (usually just a single question like "Describe Glycolysis"). Then whenever I go through the flashcards, I will edit them to clarify points that I don't understand. For instance, if I am struggling to understand a specific pathway, I will edit my flashcards and ask more detailed questions to help jog my memory. Eventually, after multiple passes through the question, I can ignore the edited question and answer "Describe Glycolysis" question without a memory jog.
It definitely takes me longer than most to go through my Anki cards, but I make 10-12 cards per lecture (Usually 40-50 lecture slides). And I can usually pass through them in around an hour and then I am good to go. Please note that I didn't start out this way. It used to take me a solid three-four hours to go through lecture material. Also, I am a SLOW learner and this seems like the best method for myself.
A little more background on how I make my Anki cards, if I have a lecture on Immunology and seven of the cards pertain to T cells, I will group them all together. That way I can look through the cards and figure out where I am missing information. Like I said, the max amount of cards I have had per lecture is around 40-50 and that was a dense Cell Bio exam (I hate cell bio). Let me know if you have any other questions, because it seems we have similar learning styles and I found out the hard way on how NOT to study lol. Good luck, OP
