The practice exams from Books 6 & 7 (as well as the CFA mock exam), with proper time constraints, is a better gauge of your performance on the actual exam. I'll even say the actual exam is easier than the practice exams.

QBank is better utilized to reinforce material learned from the readings.

I'll rank it as follows in terms of level of difficulty (most difficult on the right):

QBank --> actual Exam --> CFA mock exam --> Book 6 --> Book 7
