Mock test formation referring, multiple, testing, package, making

EastCoastJ

I know the CFAI gives one mock with registration, and Elan has one free mock ( 1 session though), when you guys are referring to multiple mock scores are all of you referring to the Schweser Mocks ( 5 6 mocks that come with)?

Unfortunately, I didn't buy the Schweser package, but my buddy has the Schweser Q-Bank (4200 Questions). I am thinking of making tests of 120 questions out of it and testing myself.

Do you guys think that would be representative of a CFA mock, the Schweser random question bank? I don't know what else to do with mocks? Can anyone give me some suggestions surrounding mocks
