That exp is saved towards the next rank. You'll see it in your profile in game, that your exp would be 100 more than required. You can only attemt one test every 24 hours though, even if you succeed. You can keep gaining exp even if you fail the test. At one point one test was kicking my ass, and by the time I got to re-try it, I had enough exp for the next rank, but still had to wait 24 hours for that.
