Related to making questions from the books or just mock exams

Hi everybody, I need your council if I may:

Because of time pressure I did not any single questions in the books material (CFA and Kaplan), now I am studying and making mock exams (my grades are 65% - 75% on average) . What is the strategy you recommend to me?? Keep making full mocks and studying or try to make full mock exams studying and all the problems within the books?? The reason I am not making questions all day long is because I dont feel 100% ready to leave the studying part, I dont feel so ready yet, but I am a little relieved by my most recent grades on my last mock exam (on the CFAI website) that was 76% am and 75% on the pm.

Thank you in advance!!

Your help is appreciated.
