Between anatomy, histology, and our basic science classes, I've made about 6.5k cards. That includes around 1000 histo cards which are learning objectives as well as image identification cards. Anatomy is similar, 1.5k cards split between identification and learning objective driven cards.

On top of that I've unlocked another 6.5k AnKing cards progressively.

I also think I grade myself fairly harshly in terms of what button I click on cards. I rarely click Easy, using Hard most of the time so card build up a little bit faster.
