I would not report my 3rd score unless it was above 700,
That's not how it works.
If you want to see your score, then all previous universities to which you have sent your scores will also be granted access to this third score.
And if you find you messed up and want to cancel the score, then the universities will also be able to see that you canceled your third score, and they will deduce you weren't happy with the way the test went on and this third score would have been even lower.
690 is good enough, it's the "700" holy grail that's owning you.
If you do take a third attempt I do hope you score big and I'm sure you will, but is it really worth it...
