Hi there!

Well admission to any institute is depends on various factors like:

1- Difficulty level of examination

2- No. of seat available in institutes.

3- Rank of the students

4- Closing rank which is decided by authority.

Every year cut off is determined by authority, hence the students who secured minimum cut off marks are eligible for applying to the institute in which they desire but the admission is totally based on the closing rank of program.

Those students who is having minimum rank has chances for getting admission into the colleges.

Let us suppose 100000 students appeared in exam, out of which 200000 students qualify exam, and let us assume there are 20000 seats in colleges across the country so according to the rank first 20000 students will get admission, and it goes on to the other rank students

However there are some reservation quota too, where some seats are reserved for category students.

I hope this info will help!
