Level 3 repeaters - help seeked

I attempted level 3 last year and my worry was always the essay questions. did my studying from the CFA texts and did not do any practice/mock exams. To my surprise i did quite well on the essays and ended up with pathetic grades on multiple choice questions… which i thought i did quite ok with! (i mean thats the stuff we’ve been doing since level 1… multi choice questions!!) This time around… i dont know what to do! if i did well on my essays means i understood things well but i screwed by the multi choice. HELP/ADVICE desperately needed.
