I sat for the GRE today, expecting to perform much better than I did. The test center had issues with connecting to ETS and I wasn't seated until three hours after my scheduled test time. I arrived an hour early too, so I waited four hours before taking my test. Obviously I was tired, hungry and emotionally drained from the waiting and possibility that I wouldn't have the opportunity to take the test in time to submit applications.

I'm so upset right now, I feel like life was turned upside down by this one horrible testing experience.
