Generally cutoffs changes every year as it depends upon various factors like difficulty level of the paper, number of students appearing for the paper, performance of the students in the exam, etc.

But in general considering previous year cutoffs then i don't think you can get CSE under 2A(General) or even Rural category as last year the closing cutoff was around 3600 for 2A general and 7800 for 2A Rural.

All the best!!
