Yes it is possible do mail (exam logs @ proton. me) as they helped me clear my 4 backlogs from vtu I hope it will be helpful for you also they helped me clear within 30 days time

Dear student,

No its not possible to clear your backlogs by paying money to the university, you have to clear it by giving the improvement exam the best you can do is to score high marks in the internal exams so you have to score just enough to pass in the semester exams.

And you can contact to your concerned teachers to get the important questions and notes and study well you will definitely clear the exam, Good Luck!
