>finished on saturday morning (two days ago).
>received grades this afternoon
>0/100
>my 98.8% average dropped to a 64.5%.
>have no fucking clue what went wrong.
>there is no way I missed every single question on the exam
>either I submitted the wrong pdf (I don't think I did that, I remember double-checking) or I am suspected of cheating (which I didn't do).
>worst case scenario, it was a bug in our open source online homework platform
>I have fought against such bugs before, it rarely ends in my favor
>swear to fucking god I'll withrdraw from enrollment and join the navy if this doesn't end well. I am tired of playing the online student game as a resident student.
I have no fucking idea what I should do, short of talking to the prof during his office hours tomorrow. Should I talk to my advisor? He's respected in the department. Would he be able to help if this goes south?
