you can def wear stuff, the issue is if it has a hood, test centers can be cold so it would be silly to not let you wear something, just wouldnt have it be some big obnoxious coat you wouldnt be comfy wearing if it happens to be cold in your room.
Thanks Allison! This is very helpful! I won't study like crazy this time around. I will try to write explanations and analyze my mistakes rather than rewrite tons of full PTs.
