I had a final exam yesterday. About 20 minutes in, I had to use the restroom (unfortunately, I drank 2 cups of tea later than I should have), so I asked my professor if I could go. She hesitated for a few seconds, and told me that I couldn't go unless I REAAAALLY had to, because it was an "in-class exam." Needless to say, I was a little surprised, but I sucked it up and said that I would wait, but I might have to go later (it was only 20 minutes into the exam, which ended up taking 1 and a half hours).
Probably 30-40 minutes later, I was on the verge of exploding, so I went up to her and told her that look, seriously, I am about to pee all over myself if I can't go to the restroom. She hesitated again for a few seconds, and then said fine, but hand me your test first. I say sure, and semi-run to the toilet. I do what I need to do, and come back within a couple of minutes. When I come back, my professor says, "you can't add anything to Part A" (there were 2 parts, A and B). Having only finished half of A, I was stunned, but my shell-shocked self told her, fine. I go back to my seat, think about it for a few minutes, and decide to answer the other option for Part A (I had chosen #1 for Part A, so when I got back I decided to do #2, a completely different question, instead). I do that, finish my Part B answer which I had nearly completed before leaving the room, and submit my exam. I tell her that I answered #2 of Part A instead since she had told me I couldn't add anything to an incomplete #1, and that I hoped that was OK.
She thinks about it for a second, and then tells me that no, it's not ok. At this point, I'm starting to get angry, but I contain my frustration. I tell her, look, I know you told me not to add more to Part A, but I answered a COMPLETELY DIFFERENT QUESTION instead. How is that not OK? No matter what I say, she declines to count that part instead.
Although I think not being granted the ability to use the restroom is a little strange, I can see what my professor was thinking. She thought I could have cheated while outside of the room - when I was arguing with her at the end, she literally said "I don't know what you did out there." My major problems are that a) she didn't tell us before the exam started that we wouldn't be able to use the bathroom, and b) she didn't tell me before I went to the bathroom that I would forfeit my right to completely answer a question.
And if I were to have cheated, hypothetically, wouldn't I have looked for the answer to the question I was actually answering? It doesn't make logical sense that I would have looked for the answer to the #2 instead (which, I repeat, was a totally different question).
Am I right to feel that this is unfair? It seems like she is treating this being guilty until innocent. This exam is worth 40% of my grade, so while I'm an unconfrontational person who hates arguing and grade-grubbing, I feel that I have the right to do something.
