So I made stupid mistake last night. I submitted the wrong file for my last assignment for my c class. It has no header, so I got 30 points deduction. I worked on the program for a week. I couldn't make it work as it is should be, but I know I should get at least 80 points. But because of my stupidity I only get 50 points! I worked hard the whole semester to get A grade, but now I can't make it because my carelessness 😞 I feel so upset..
I need to swallow this bitter pill, learn my lesson and move on.
