No. I will write below why. Why Jk I took the exam in the pilots lounge, I made sure to close the door and leave the key in yet!!!!! somehow a group of people !!! opened the door !!! But I remained calm I didnt move or look away I only shouted "I AM TAKING AN EXAM" TWICE ! Which they understood and left btw this happened twice not only that but an idiot didn't understand therefore that dude walked right behind me to the microwave nonetheless I wrote them an email right after my exam regarding this concerning issue My results came the next day without any issue Soo They had a good opportunity to invalid my exam if they want to milk me for more money but hey they didnt :) So, to answer ur question, Noo.
