It depends on you. If a general idea or a trick to be followed is to be given to you, then I'll personally recommend you to initially mark only the answers that you are confident with. If you've prepared sincerely enough for the exam, I guess around 120-150 such questions will surely exist that you'll be able to crack quickly. Well that gives you around 360-450 marks in a jiffy. Now the competition begins. You've to be very smart now. You can start using your time on questions that you can think harder, solve harder and try to reach out to answer. You can also use the method of eliminating the options and then choosing the one left. Some smartness you can use and go on for answering around 20-30 more. So even if 13 out of 20 are correct, that gives you a advantage of 13*3 - 7+1 = 32 bonus marks. So you can try out such permutations and combinations in the examination and then figure out the best for yourself.
