Today I survived the GMAT Online!
Before anyone asks, this is my best guess at my scoreQuant: 49-50 (had to guess on a few, the online whiteboard was not so bad, though the hard ones would have been easier to "churn" on with an actual physical note-taking component)
Verbal: 40-51 (Verbal is always the wild card, imo). I will admit that I took the test late at night and went really quickly on Verbal--I finished with 25 minutes to spare, but I didn't feel rushed and I read every RC passage all the way through, for meaning.
Composite: 730-770IR: I tanked the IR section because the test failed on me right at the beginning of the section, and I totally lost my flow. I was able to get back into the exam just fine (thank you to my proctors!!) but I got a very ominous "test failure" type message that terrified me and made me fear for the worst. Ultimately, it spooked me and I was afraid that--like others whose stories I had read here on GMAT Club--if it happened again, then I would not be able to restart and I would be forced to retake the entire test, so instead I guessed my way quickly through the rest of the IR section.
Probably a 2 or 3, 4 if I'm lucky.
