Stalla Vs Schweser?

Hi everyone I am about to enroll CFA level I and I don’t know whether to buy Stalla or Schweser stuff. Could anyone tell me which is the best decision?. I don’t care about the amount of pages, I just want to make sure I get the most complete. Regards

Stalla for Level 1 and 2, Schweser for Level 3

Try that thing called the “search” feature.
