look, this would work if you could approach each question asking "do I know this 100% for sure?" If yes, then select correct answer. If no, randomly guess. Then you would be correct. But the reality is that we are never 100% sure that we know the correct answer. There is always at least some doubt. Now also consider the case where questions are designed to create additional ambiguity and doubt.

Your perspective is a 'law of large numbers' perspective. I.e. take enough random trials and you will approach 1/n. What I am talking about on the otherhand and what I think is reality for CFA candidates is that for each individual question if we don't have the material down COLD we will more than likely fall for a 'distractor' option and score zero for that question. Also, the correct answer will unlikely present itself as an attractive option to those that are less than fully prepared so for the 'prepared' candidate the chances of unwittingly CHOOSING (not guessing) the correct answer is very small. And that is to say NOT RANDOM.
