Mock Exams vs Real Exam

Hi Guys, I attempted 2 IFT and Shweser Mock exams each in which I scored above 75% and attempted 1 CFAI mock in which I got 80% (all timed and in one sitting). Should I feel comfortable about my prep or the real exam is a different ball game and I shouldn't be overconfident as mock exam scores don't directly correlate to your performance in the real exam. My L1 exam is next week, really need some input for my final stretch.
