hello Khusbhu,

In every college, semester exams are done in two phases, the first is the one which you missed. To aid the students who missed their first phase exams or who could not clear the exams, the college conducts exams for those students again. This is called phase two examinations. So now what you have to do is apply for phase two exams in your college. Meanwhile, you can join semester 5. But you have to clear the semester 4 exams in phase two  to keep continuing in the 5th semester .
