What's the deal with the optional break?

What’s the deal with the optional break? Can you eat or studying during it? Are you allowed out of the room? Do you plan to take one?

you can pretty much do whatever. you aren’t allowed to go back to the first section of the test… so you can leave the room, eat, drink, whatever. if i were you i would take the break - only because it gives your brain a break. grab a drink of water… clear your mind… for level 1 time isn’t a huge problem, but because it’s 200 multiple choice it gets a little tedious. take the break.

I partied during my break.
