The tricks, you must decide whether you want to keep your scores before the computer shows them to you. If you cancel, your score will be disregarded. Canceling a test means that it won't be scored. The score will not be known to anybody, even you. It will appear on your score report as cancel test.
If you do cancel, your future score reports will indicate that you've canceled a previous test. But since the canceled test was never scored, you don't have to worry about bad numbers showing up on any subsequent score report. If you take more than one test without canceling, then all the scores will show up on each score report, so graduate schools will see them all. All GRE testing administrations will be listed in your ETS record for five years.
