Is this a dumb idea

I'm a senior in highschool. I know. I know.

But I use anki to study for my classes, so far I've done AP Bio/psych/chem/calc. I'm doing highschool physics and intro organic chemistry and biochemistry rn.

Given I have some background in the STEM topics, obviously not enough but still, I was wondering what if I install a MCAT anki deck and do like, 5 new cards a day slowly over the next few years. Since there's spaced repetition I wouldn't forget it. Is this dumb?
