Hello Ch Ben,

Congratulations on scoring a decent score in SRM entrance exam. Getting a seat on in a college is predicted on the basis of closing rank of previous years.I am listing below the closing rank for last year for CSE branch of different branches of SRM :-

SRM,Chennai        CSE        Closing Rank - 10000

SRM,Ramapuram CSE         Closing Rank - 65000

SRM,Vadapalani   CSE          Closing Rank - 68000

SRM,NCR             CSE          Closing Rank - 54000

SRM,Sonipat        CSE           Closing Rank - 68000

As you have got 45000 rank your chances are slim for Chennai campus,but you have a decent chance of getting into other campuses.

Do let us know in comment section if you have any other query.
