I have taken 2 250 question exams 1 on cccure and from sybex, cccure i got an 86% and on the sybex exam i got a 73%

, is this good or bad? keep in mind i took both exams back to back 500 questions straight (i know burn out) My exam is tuesday, should i take more practice exams or focus on reviewing notes? Any advice helps. Also after reviewing the sybex exam i found about 10 or so questions that i just misread the question.
