How many times before passing & strategy?

About to give up after failing the second time.

Passed on 2nd try.

Used Schweser 1st time, Stalla 2nd time, did not touch CFAI except for Ethics.

What did you think of Stalla vs Schweser? I failed with Schweser the first time and am trying to figure out who to use

I liked Stalla notes and videos. Had to buy schweser Qbank. Stalla’s Qbank sucks. Now, not sure if either are better than CFAI books since I haven’t passed yet.
