It is difficult to predict about the seat allocation in any institutes, as the admission is totally based on closing rank which is decided by institute itself and it depends on various factors like:

1- No. of seats available in institutes

2- No. of students seeking for admission

3- Rank of the student

4- Category of an individual

and many more, but we can get a rough idea of closing rank by analyzing previous years trend.
