So, despite what you said, you didn’t actually want any advice it seems.
Caveat emptor…
Here’s a typical comment from a TCMPC examiners report regarding pass rates; first for the case studies paper and second for the MCQ paper. As you can see more that half of all candidates across the country failed their case studies exam, and more than a third faild the multi choice.
"The PASS MARK for this examination was 32 and the PASS RATE was 45%
The PASS MARK for the multiple-choice question paper was 42 and the PASS RATE was 59%."
