To be honest with you, 70% is good but it is quite generous. For our mock exams in the program, you should be striving for the highest marks possible.
Here’s the thing: Each mock exam has parts of it that expose a weakness in a TCM topic. Let’s say I have five practice exams to prepare me for the real thing. If I get 80% on five exams, that means that I got 20% x 5 wrong. I got 100% wrong.
I know you know this, but I have to say it again: the reason we write mock exams is to expose any weaknesses of our education. Then, we study. Then, we retake the exam and see if we shored up that weakness. Rinse, repeat. Now go crush those mock exams to prepare you for the real thing!!!
