Greetings of the day dear Yash

Firstly, congrats on successful completion of your SRMJEEE Examination with flying colors. The cut-off trends keeps changing every year and it depends on the number of students attempting the exam, difficulty level, number of available seats, etc. Getting a CSE seat is getting highly tough these days as the demand is very much. But, with a rank around 800, you can very easily secure a CSE or any seat of your choice in SRM KTR Campus as the closing rank was around 9,500 - 10,500 for CSE core branch in SRMJEEE 2016. So, just apply to their counselling process and secure a seat easily.
