If you go through the last 4 year cutoff list of C V Raman you can find that with 4lac+ rank in JEE mains one can get any stream in CV Raman if he or she belongs to Home State. So, if the HS Quota is applicable in your case then you can even get CSE Department for sure if everything goes well but if it is not applicable then it will be tough to get any top branch in this college.
