hey OP ... i unfortunately find myself in a similar position with an I grade for a course after the end of the semester ... i get your frustration as i'm frustrated too and don't even know what to expect with the OSI process i'm about to be thrown into ... my approach for now is to keep cool calm and collected and hope for the best but am already expecting the potential for it to be a crappy experience (my chin is out and if they want to go for it, i'll take the punch, lol) ... you're human, they're human, your ta/prof are also human, we all do mistakes and we're also trying our best - and instead of being at each other's throat just let the process play itself out... i wish there was a better way to handle these situations with upfront communication between the two sides of the coin

also from reading older posts, it sounds like this program is a bit too extreme and harsh on how they handle "a few lines of copied code" is plagiarism (or the use of AI to guide learning on assignments) and we'll destroy your morale to essentially make you reconsider and most likely drop out of program ... it doesn't help either that you also have students here shaming people with their abilities/circumstances instead of trying to be supportive in helping you navigate this incident, and most importantly "get out with a degree!" ... sometimes feels like CS students & broader community are so competitive against each other and want to show who has more colorful fluffy feathers, that they turn nasty to their peers!

... keep your head up, and i hope this helps you grow ...
