When it is 10 degrees outside in the dead of winter, it is kind of hard to go chill outside. Just going to the bathroom and pacing around the waiting area for a few minutes will usually eat up a good chunk of your time.

Also for time management, the recommended times shared in your study materials or simple Google searches are pretty spot-on. About a minute or less per multiple choice, and leave yourself a good hour for each TBS section (x3). So roughly an hour for MCQ, and 3 hours for the rest of the material.

Also I have never done a one of those full practice exams that is provided with your study package, but I can imagine the pacing/intensity/environment will be different, so I really would not expect to understand what it is like actually going through an exam until I actually went through one.
