same thing except when I do mini-mocks I show improvement for QR but when I do the practice time-limit I get lower than I do in the mocks, and it's the opposite for verbal reasoning, I think it depends on the type of questions you get given.
You'll be fine so long as you keep on practicing, then at least you know you tried, mines at the end of sep on the 21st and I honestly think I'm going to blow it..
Good luck for your exam, best tip I can give, is to relax like the day before don't stress yourself out, do some questions on the day of your exam, not too much, also go back on all the things you get wrong, you never know similar questions could appear on the test day.
