the present system deals with credits per subject you passed. according to it you should have minimum 45 credits till 3rd semester so that you can move forward into 3rd year.
And as u have just one supply.. which means on a maximum loss of 4 or 5 credits as per the subject.
still you have 40 credits in hand ..
and to secure 5 credits in s3 is not a big deal..
so, there is no chance for an "year out"
