I know you're halfjoking, but tough quizzes tend to have a few antiQF problems in them.
To make the math simpler, let's assume we have 9 questions with 3 choices each. Random guessing should get you 3/9.
This suggests that the optimal number of antiQF problems is 3. If there are 3 antiQF questions, then you'll get all these wrong with your strategy, and you'll get half of the remaining 6, again for an expected score of 3/9.
