Schweser QBank vs Practice Tests difficulty, practice, compare, create, pretty

hinsafdar

The Qbank lets you create a simulated exam (Up to 120 Questions) with CFA topic weighting. It's pretty much a semi-random sample of the 4000+ questions that the Qbank gives you.

How does this compare to the practice tests that Schweser has? Which is more difficult? And which is a closer representative as to the difficulty of the real exam?

Thanks.
