GMAT is a computer adaptive test and thus, the level of difficulty of questions increases if you are doing well and decreases if you are not doing well.
You can neither skip any questions nor can you get back to previous questions.
First few questions are very important as your raw scores fluctuate a lot in the beginning. Towards the end, the scoring system is relatively less sensitive. Hence, while all questions are important, the first 10-15 questions in each section are relatively more important.
On GMAT, you are penalized more heavily for wrongly attempting few questions than for not attempting them. Hence, please make sure to attempt all questions and if you are running short of time, make sure to randomly mark all the questions.
Before you start with the test, you will be asked to name five schools to which your GMAT scores are supposed to be forwarded. For every additional school, you need to pay $28. Hence, please be prepared with name of five schools to which you would like to forward your score.
Avoid multiple attempts at GMAT. It’s not only wastage of $250 every time but also harmful to your profile as GMAC would be sending scores, to designated schools, of your all the GMAT attempts in last five years.
After you finish your test, the system would ask you whether you would like to see your score. If you are sure that you have screwed, you can opt not to see the results. In such a case, your test would be deleted and no score would be sent to any schools.
Almost 20-30% questions that you see on GMAT would be dummy questions and you would not be scored on them. However, there is no way to identify such questions and you should attempt all questions with equal seriousness.
To reschedule your appointment, you need a gap of at least seven days. Take a GMATprep test (freely available on www.mba.com) 8-9 days before your GMAT and if you don’t score your target score+10-20 points, get your test rescheduled.
