Dear Tapish,

I hope you are fit and fine.

Now, If we look at previous year cutoff trends then we will find that the Computer Science and Engineering seat in SRM main campus has been given to students whose rank is below 6500, so you seem to be holding a some chances to get CSE in the main campus.

Other branches that you can also get there are mechanical engineering,  chemical engineering,  civil engineering,  aerospace engineering,  electrical & electronics engineering etc.

In case you want to know more about the cutoff of SRM colleges in detail, you can follow the link below.

I hope this information helps you.

Good luck!!
