I used the QBank as well, and while it is useful for practice questions it definitely does not reflect questions that you would see on the exam. I suggest you spend a lot of time on the CFA EOC questions (even the open-ended ones) and not worry about solving each and every question on the Qbank.

The Elan mocks were great because they had conceptual questions that tested your understanding of multiple LOS. Elan is planning to release their practice questions in August. I would definitely get my hands on those.
