CFA Level 3 study guides

[AspirinCountTheory]

I know I’m jumping the gun considering I haven’t passed level 2 yet (fingers crossed and good luck). But i was wondering if anyone knows how mock exams are graded for the level 3 practice tests (bc they are essay). I have been using kaplan for the last year to study for the exams and im wondering if that is still the best option for level 3. I rely heavily on the mock exams for studying and gauging my progress.
Thanks guys.
