Not really the concept checkers are pretty light weight. I did about 1/2 of the EOC’s I think at this point you would be better off doing the Mock exams they give you the 6 exams plus the CFAI mock.
It will conservatively take you 30 hours to do the EOC’s, 17, 18 alone are about 6-8 hours. I think allot of the people you see scoring high on the schweser books are 2nd timers.
