Dear aspirant,

I would tell you some of insights of some of the colleges like what they do. For example, vit vellore - The college even takes money for re exam to clear backlogs and approximately 5-6k so it won't reflect in your final result that you had a backlog.

Similarly there are many private universities which follows this rule but in case of government premier colleges it would reflect so it depends on which college you are. But as you mentioned it was in 1st year. It won't matter much. But no one takes any chance.
