How do you request the free GRE score reports to schools?

[gomeperez]

I just registered for the GRE and I didn't have any section asking me for universities' information to send the scores. I read that you have to write them right after you finish the exam..

How does this work? Do I have to remember all the codes for test day?

You do it on test day. No, you don't have to memorize them.You can look them up.

But it is likely a good idea to know in advance where you are sending things...some universities have multiple options for score submission, and may have particular instructions for which unit to send them to. Additionally, some of the schools have multiple numbers because older or otherwise currently defunct accounts with ETS have not been removed from the pulldown list on the test.
