AjiteshArun Thank you! I'm just really nervous because the proctor was clearly not in a very good mood because no matter how many times I apologized, she just kept repeating to me that I had committed a testing violation and that the GMAC would be reviewing the video footage so I'm assuming that means she's reporting me?
Technically, she's correct: you had agreed not to get up from your seat without being escorted by a proctor when you signed the GMAT agreement. If they decide to go strictly by that agreement, your score will be cancelled. However, you did not bring anything into the testing room, nor did you access anything (like books, a phone, water, food...) during your exam. Moreover, your exam was over when you got up, and you did not disturb any other test taker while leaving the testing room. This means any cancellation will be purely to "go by the rules" and not to prevent the use of unfair means.
I can understand why you're feeling a little nervous right now. Try not to think too much about what could happen, as there is really no way to know how strictly they'll apply that rule. Hope that this goes your way, but be prepared to take the exam again.
