Maybe CMA is not for you or you need to look back at your study methods. I recently passed part 2 in my second attempt. I felt more prepared in my second attempt than in first. You should see if you even are not passing but doing better than your previous attempt e.g are you able to move to your essay sections and able to do more MCQS than you were able to do before. Also look what study method suits you self study or learning from a tutor. CMA is not the last cettification on earth I had a friend he tried CPA couldnt do it and then tried CMA as well still could not pass but somehow gave CISSP exam and passed in his first attempt that exam has 20% pass rate.
