Can we change the internal marks of a failed subject at VTU?

Yes, you can change internal marks if you are writing the back paper in the next semester’s exams. Internal marks are sent to VTU before the results are declared and the college displays the marks allotted to be cross-checked for any errors before sending the finalized marks.

Students can take up the internals and increase the marks before appearing for a second attempt.  

But if you are applying for external revaluation and want some increase in internal marks, that is not possible.
