First time proctored test taker

Hi! I started Jan 1st and going to take my first proctored test this Friday 1/10 for Organizational Behavior - C715. Can anybody tell me how the testing process goes? I’ve got my Webcam 1000 ready to go. Will testing in my dining room be an issue? I’ve read about proctors being absolutely horrible and the thought of that makes me really nervous… Any tips or advice?
