Anyone tried Passmaster for level II?

I tried it for Level I and it was super.

woked for me in lvl II did the stalla course (passmaster lectures, etc…) + CFAI exams

What is Passmaster? Is it Q & A from Stalla? Can someone please shed light on how different and useful it is compared to Schwesers?

I thought passmaster broke down too much, and I found the questions a bit too straight forward… Not to say that it wasn’t helpful… I havent had any exp with schweser QBANK…
