I checked it after completing Exam 1. But the one mistake that one of my friends made, was wasting time circling it on the booklet that you get to keep as well as the MC Sheet at the same time. He should have done the whole exam first, and then copied it out, not at the same time - Otherwise you are wasting time and will not finish. He ended up guessing about 2 or 3 at the end (which isn't too bad), but its still costly marks. =/
So do the whole exam first, and if you have time at the end, then copy it over to your question booklet.
For those wondering how you can mark your Exam 1 (Multiple Choice Exam), the Solutions for each exam will usually be up on iTute on the night of the exam (So on the Friday at night), or within 24 hours of Exam 1 being finished. They are done by teachers, so they COULD also be wrong - Usually not dramatically wrong though.
