Hi there,
9900 is a good rank in SRMJEE and you have a lot of options available to you.
Considering your question, I would like to tell you CSE cutoff for different campuses for the year 2018 are as follows:-
1) SRM Chennai:- 10,000
2) SRM Ramapuram:- 65,000
3) SRM Vadapalani:-68,000
4) SRM Ghaziabad:- 54,000
5) SRM Sonipat:-68,000
So, as you can see you can get CSE in the main Chennai campus, but it is a little bit on the luck as you are very close to the closing rank.
All the best.
Thank you 

Hello Arnav,

As per previous year cutoff trends, in 2016 CSE in main campus was closed at 10k. you see, cutoff fluctuate upto a certain bit. It may either rise or fall. If it rises that is goes above 10000 then there are vague chances that you might get CSE otherwise none at all.

I am attesting a link for your refrence  for other campus go through this link https://engineering.careers360.com/articles/srmjeee-cutoff. This link specifies about cutoff trends of previous year. Go through this link in order to get some insights about various other campuses of SRM and their cutoff.

Your rank is pretty good. you might get many more different branches in main campus.  I think apart from CSE you can get all the branch from main campus, that's the reason I am providing you this link. Moreover, there are other campus of SRM too which are decent too. 

Hope your query is resolved. If in nearby future you need my assistance, then do inform me.

Wish you best of luck in your future endeavor.

Hi Arnav!!! Congratulations on your rank. I am glad to inform that you can surely end up getting CSE in the main campus. If we go by the cutoffs of last year, Cse cutoff of chennai campus last year was 10,000 rank so you have a good chance.

Wish you all the best.
