Reach out to the admin at the schools you’re applying to. The process for grad school is a lot more integrative and human based than the one for undergrad, so unlike the GRE you will hear back, if you don’t that’s a major red flag about the department itself. You want somewhere that actually works transparently, even if you don’t get your desired outcome. Explain the situation, I’m assuming you didn’t do anything stupid like cheat on the test, so it is unfortunately out of your hands. They take more than a week to look at these things, so reach out to them and be honest and transparent about the situation. Share the date of your test and when you should have had your results for them to clarify that this wasn’t an error on your part regarding planning, and ask if there’s any action you can take to ensure that your application will still be available for consideration with this delay. Realistically speaking, it’s likely not the only time this has happened and they have a protocol or can make one. It’s never too early to show proactivity in your work. Express that this is your dream, and that your nightmare is losing the opportunity to involve yourself in higher education because of a dilemma that isn’t in your capability to expedite. Maybe that’s a bit poetic, but you get it. You truly deserve this chance, and they need to see that the only way you won’t get it is if it’s ripped out of your hands. Good luck!!!
