I actually had a very positive experience writing in June. As with the others, the check-in process took about 5 minutes and the proctor was very pleasant and had clearly switched proctors several times during the test but didn't notice. I drove myself crazy worrying about technical issues during the test, but as long as you have consistent wifi connection, you will be fine! And from what I can tell, ProctorU is getting better at administering this test with each cycle that passes, so it's likely that things will go even more smoothly by July!

Is this only open to American students?
