Hello

Yes of course, summer semester are ment for that purpose only. But you will have to pay extra for you accomodation and mess charges(around 10000), apart from that, it is 6000 per subject(approx).

I suggest you to not wait only for 1 subject in summer semester, instead you can take around 3 subjects, so wait untill 2nd year, maybe you get another N grade.

Hope this Helps
