I have started studying CFA seriously for the past 1 month, but keep getting the exact same range when doing Schwester book exams (did 9 tests, AM PM separately), and the range is from 65%-70%, very consistently, with ethics 66.66% consistently. This kind of consistency kills my sleep... CFAI sample test got 92% last week (think this is just outlier) and haven't touched CFA Mock yet.

My confidence level now is 30%, as if I never feel worst than before. Should I continue reviewing and do the rest of Schwester exams & QBank (only finished 1/3) or should I jump into CFAI mock now? I really need luck in this exam...
