The significance of a rise in serum αFP

I think that's mainly an example where it's not straightforward to make good cards.

Basically I would get a list that rise in serum αFP does X, Y and Z. Then I would make cards:

Does higher or lower serum αFP does X?
Does higher or lower serum αFP does Y?
Does higher or lower serum αFP does Z?

I personally formulate the cards a bit differently but that's the core.

Ven diagrams/etc, to compare and contrast similar lists. (This is more specific to medical school, when you learn subtly different diseases.)

I do have Anki cards that contain Ven diagrams. At the beginning the Ven diagram is shown empty and the user is asked where a given item belongs on the Ven diagram.

As answer card the whole Ven diagram is shown and the item that the user had to place is highlited with a special color. I haven't yet automated the production of such Ven diagrams but I think that's part of the future of Spaced Repetition Learning.

Your mileage may vary, but after seeing so many people try and reject them, I figured it was enough data to share. Mnemonic pictures and memory palaces are slightly time consuming when you're learning them.

If you want to learn information the day before a test and get a good score then Anki won't help you for that purpose. That's not what it's made for. Anki exists to prevent you from forgetting information. There a good chance that you will forget your memory palace information in a year. Especially because memory palaces have a reuse problem. If you use the same palace for multiple lists you get conflicts.

Your mileage may vary, but after seeing so many people try and reject them, I figured it was enough data to share.

I would guess most of those people violate various of Wozniaks rules. If I look at the most popular Anki deck about medicine that's on Anki shared deck list I fully understand that learning that way isn't optimal.
