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.
bubbling at the end of each section is totally cool as long as your Proctor gives you your test back during the break saw this done when I took the October LSAT. Definitely a terrible idea to wait until the end of section to bubble in.
