First of all, hats off to you for being guinea pigs for this new universe of LSAT testing. That would be nerve-wracking for anyone.
If you’re feeling lousy about your performance, or you know you messed up certain sections, or you messed up the timing and didn’t finish a section that you normally finish, THAT’S COMPLETELY NORMAL on the first test, whether it’s Flex or not. There’s some little part of our lizard brain that always knows it’s a real test and not a practice test, and it usually freaks out on the first test, and even more so when there’s a big change like this in the test format. That’s why so many people perform worse on their first test than they did on their practice tests. Happens all the time.
That’s why I always recommend that you plan on taking the test twice, and budget that into your application timeline. The second time around, your lizard brain is a bit calmer, because you were able to shake out your nerves in the first test and the retake doesn’t feel so weird.
So if you’re not feeling good about June, should you cancel your score?
Because the June LSAT-Flex is not a disclosed test, you won't find out which questions you missed. In that case, there's no upside to keeping the score, and there's no downside to canceling.
And if you ever had cover for canceling a score, it’s this test. See above, guinea pigs. Admissions officers won’t even blink if you decide to cancel this one and retake.
For reported tests, it can be useful to get that test info back to help you prepare better for the retake. But that’s not the case with this test.
So there are no bad outcomes here. Rejoice!
