I myself got, 82% and 78%, but failed the ethics portion as I thought it was a lot harder than Elan Guides ethics, aside from that I thought the Mock was relatively easy. Your scores are good, assuming that the passing grade is somewhere between 65% and 70%, you have a solid 20 question or so buffer based on the scores that you got in the mock, so I wouldn't worry if I were you, just make sure you maximize your performance come Saturday. People looking for the 90% + on these mock exams simply arent being realistic, the institute has over 2,000 pages of curriculum to pull nit picky questions from such as the different economic theories, qualitative characteristics of financial statements and so forth, in my opinion not even worth attempting to memorize.
