There's a 15-question survey at the end of the exam before you get your scores. You may be able to skip past it because there was an "exit" button, but I forced myself to take it because I'm a psycho/masochist? Idk.
But just a heads up, the survey will pop up. I know someone who got a little bit of tunnel-vision and when she saw "15-questions", she thought she got a 15 and freaked out lollll so don't let it happen to you!!
