How many times should I take the GMAT?
You can take it ones, or several times, according to your wish. The number of attempts is not limited, but many business schools will average your scores. Contact schools you are interested in and ask what their rules according to this are. Then plan your strategy accordingly.
 
Is it possible to cancel the test score?
Yes. When you finish the GMAT test, the computer will offer the option of canceling the test or accepting it. If you cancel the test, neither you nor any school will see your score. If you accept the test, the computer will display your GMAT score and it will be available to all schools.
