Do not read all the questions through first. You will waste much less time if you just read each question as you come to it.
Read all the alternatives. The first answer may be a good answer but it may not be the best answer.
If you do not know the answer, eliminate those that are definitely wrong and then select your best guess.
Do not spend long working out the answer. Keep in mind how much the question is worth.
Do not change answers for questions you have already completed unless you can see an obvious mistake. In most cases your first choice is more likely to be correct.
