So the problem is something like this: Whenever I upload the grades using CSV, I am successfully able to do it. But in the grade view (Grades -> View -> Single View) adjacent to every student grade the override checkbox is ticked on. If I untick it then the marks uploaded to that particular student disappears. If I keep it ticked on, then students are able to see the grade but it would be still showing that assignment is not graded, in spite of uploading the grades. Some of the TA's at my University have used a bad approach to this problem by manually assigning marks to each and every student which I think is not good. Can somebody please help me solve this problem? Thank you so much in advance.
