I am a computer science student.If i have a back paper in the fourth semester can i take admission for pg.

If you have your back paper in 4th sem than you must be giving this paper again in 6th sem so when your both results are out, obviously passed than you may take admission in any college available at that time.

No,because until and unless u r not providing ur degree alongwith ur final results the next college will not admit u........!!!!!! So,go for ur degree first......!!!!!!!!!
