backlogs

I am a BSc student in Vivekananda Degree College, Osmania University. I joined B.Sc in 2013. I have cleared almost all the subjects except Physics 3. I wrote the exam yesterday but the paper was a bit tough for me and I don't think I will pass. If I fail, will I get another chance? My friend...

Suppose If a student had 6 backlogs in the past and cleared all of them before 4 year Does he get a star in the consolidated memo Does it affect chances in getting a seat in mtech
