I took the general GRE today. When will I be sure the scores shown at the end are official?

After taking the general GRE today I was happy with the scores shown at the end and don't plan on retaking. However I notice that there's nothing about my scores on the ETS website, so now I'm sort of concerned that I didn't exit the program correctly and the scores I saw aren't valid. Or something along those lines.

(A second question - do the unofficial scores really change in the official report? What if you got a 170 in one of them?)

Thanks!

ETS will post your entire score once the AW score is in, usually within 10 days to 2 weeks. I can't say with absolute certainty that the V & Q scores you saw at the end of your test are official since I haven't seen ETS' policy on this, but I've never heard of any incident when they were changed in the official score report. Also, I believe those sections are entirely graded by computers compared to the AW which uses human readers, hence the delay in scoring. For these reasons, you may as well consider them official and stop worrying. You're done with the GRE, congratulations! On the side note, I did get a 170 too and it did not change

The scores you saw at the end of the test are the scores you'll see on your report. And if you got a 170 in one section, congrats! That's awesome.

That's a relief. Thanks to both of you for the responses!
