I wouldn't rely on that crutch either. Say you get used to it and then your proctor ends up telling you "no gum"...just another thing to throw you off on test day
Everything you do is dictated by the proctor. When the 35 minutes are up, you absolutely cannot go back and fill in any remaining questions. You will be kicked out if caught.
Correct, you may have something like 20ish seconds in between the sections. Only enough time time for the proctor to read the 2 or 3 lines of instructions.
This is a very common complaint after a test administration and is why I do my retake tests at Starbucks. I put my earbuds in to hear the proctor app, but it's still very distractions. Prepare for the worst, hope for the best.
I know this isn't much help now but maybe for future test takers.....before the exam the proctor had everyone put their chapstick in the front of the room or in the trash saying it was a violation...good ole LSAC.
