Actual CFA Exam questions because, schedule, practice, into

liquidity

I’ve been avoiding Book 7 because I heard it is way too hard, but I just took a look at it and noticed there are 84 practice Q from 2005 and 2006 actual CFA Exams.
I didn’t make time for these in my schedule, and am not so sure I can fit it in.
Did anyone do these? What’s the feedback on them?
Is it worth cutting into other stuff to do these (keeping in mind I did all samples and mocks and Schweser book 1)?
