I suggest you ...

cards should belong to several units (maybe with different weights)

suppose you learn a unit "Addition" followed by unit "Multiplication"

when you solve: "3*4+5" correctly you should get your score up in both units - because this question is using both multiplication and addition.

In general, questions can use multiple "units" or even "subjects". When you get a question correct or incorrect it should affect the scores of all the related subjects.
