Need a good set of questions to study from

I am sitting for L1 in June.  As of now, I have prepared by going through the Kaplan guides (and doing examples and EOC questions) as well as the CFAI coursework (again, along with doing all the examples and questions).  Though I review each incorrect question (and each question I have difficultly with) I'm still not confident that I know all the material.  For example, if I get a 70% on the EOC questions, that means I know 70% of the material I was asked in that series of questions, not 70% of ALL the possible testable material.  Even though I may do a total of 50-70 questions for a given section (between the Kaplan and CFAI examples and questions) I know it doesn't cover all the testable material.  Furthermore, for topics I have difficultly with, it would be helpful to have more questions so I can do a complete job learning said difficult material.

I've read that the Q-bank questions are easy compared to what is on the actual test, so I'd like to stay away from them.  I've also heard that the Elan Q-bank is sufficiently difficult, but it cannot be arranged by topic, making it difficult to focus on areas of difficultly.  Does anyone know of any series of questions that do a good job mimicking the difficultly of the actual test-day questions that can be arranged by topic (i.e. reading 43, 44, etc?)  

Thanks!
