Arghh h - misread the question. My comment referred to how to start STUDYING for the exam – i.e. focus on the “big point” areas, and learn how to check the reasonableness of your answer.
When TAKING the exam, S2000’s advice is spot on (as usual) - go with your strengths first. I’d add that you should always put down an answer and keep moving. I
advise my students to “Code” their answers - If you are sure of the answer, put a * next to the number in the book. For those you aren’t sure about:
(1) If you can eliminate one of the three answers (let’s assume it’s “C) (see above on learning how to check whether an answer is reasonable), choose one of the remaining two and mark the question A/B
(2) if you can;t eliminate one of the choices, GUESS and code it NFC for “No F**KING Clue”.
Take a minute after your first pass through the exam (this will happen prettty fast if you keep moving) and count up how many you’re sure of. This will show you where you stand. Then go back and look at the “eliminate 1 group” if you have time after that, go back to the NFC ones. This way, you spend your time first on the ones you’re sure of, and then sequentially on the ones that you’re less sure of.
If you’ve got plenty of time, this method doesn;t hurt you. But if you’re time constrained, it ensures you spend your time where you’re most likely to get points, and you’re not spending the lst few minutes frantically guessing on questions that you would have been sure of if you did them first.
