u/Content-Extension-49

I honestly need advice because I feel completely stuck right now 😭 I’m at uOttawa and currently sitting at a 48.5% in BIO1140, so I literally need around 1% to pass the course. The whole situation mainly comes from one lab report and I genuinely don’t know if I’m being unreasonable for thinking this is unfair.
For the lab, I submitted my assignment before the deadline on Brightspace, but somehow the PDF that uploaded ended up missing my graphs. I genuinely did not realize this at the time and thought I had submitted the correct file. When I later saw my updated grade, I went back to check the submission, noticed the graphs were missing, and immediately emailed the corrected version with everything included. The problem is that after the deadline passed, Brightspace locked the dropbox, so I couldn’t officially reupload the corrected file myself.
The lab coordinator told me they can only grade the file officially submitted in the Brightspace dropbox and that there was only one file in the submission history. I completely understand policies and deadlines, and I know I should have double checked the uploaded file, but what makes this so frustrating is that the graphs WERE completed and I have document version history showing I had been working on them around that time. I even asked if they could maybe accept the corrected version with late penalties or temporarily reopen the submission folder so I could formally resubmit it, but I’m still waiting to hear back.
What’s also confusing me is that near the beginning of the course, the professor mentioned that if needed, midterm weight could sometimes be moved to the final exam. I even asked her with my friends if it’s possible and she said yes. Since I did much better later in the semester(final), I emailed asking if there was any possibility of transferring my Midterm 2 weight to the final exam instead, especially because I’m only around 1% away from passing, but I was basically just told no and wasn’t given any more explanation..
For the lab 4 I fully understand that rules are rules, but I honestly feel terrible because this feels more like a submission mistake than me not doing the work at all. I have gotten really good grades on all my other labs as well. I’ve been stressing over this nonstop because failing this course affects my entire summer schedule since it’s a prerequisite for other courses I need. I already have to retake other classes, and I genuinely cannot afford for this one mistake to completely throw off my academic plans and financial situation too.
At this point I genuinely don’t know what to do anymore. Should I keep pushing the lab issue, escalate it to the department/faculty, go to the final exam review and hope for a marking error, or just accept the loss and retake the course? Has anyone else at uOttawa dealt with something similar before?
