Sub-test 3: quantitative
To indicate your answer, put a tick alongside the suggested answer of your choice and when you have reread and checked your answer, fill in the box, then move on to the next question. There is no going back in the real GMAT CAT® so when you have moved on to the next question, do not be tempted to go back and change your answer as you will not be able to do that in the real test. If you cannot get to the solution of a question then it is worth guessing, but only as a last resort. Remember that to do well in a test you really have to try very hard!
You are allowed 75 minutes in which to attempt the 37 questions that make up this test. Work where you will not be interrupted and complete the test in one continuous period. Do not use a calculator. Do not turn the page until you are really ready to begin.
