Let me tell you what can happen :-
I am in third year , in VIT vellore. Last semester, my friend got caught cheating in lab term end by a strict faculty. A committee was set up that would decide the punishment. He was called even in holidays with his parents to appear before them.
He got semester back. That is ‘F’ grade in all subjects.His CGPA went from 8 to 6. He couldn’t get a proper room because of his low NCGPA.
It was his good luck that later the committee decided to fail him only in that subject.
