Dear Student ,

As you know CSE is one of the most demanding branches in the domain of Engineering.. so in any premium institutes , the competition level will be surely tough in this case ..

So .. as per your caste category , you should rank within 1500 (As per the cut off details 2020) to get any of the IITs with your preferred branch in Female reserved seats .

Well, you need to remember that , every year's cutoff in IITs depends on some following factors :

• No of Students appeared for exam
• Seat Matrix
• Difficulty level  of exam

refer to this link for the detailed cut-off trends of previous years for CSE branch through JEE ADVANCED:

Hope this helps !

Best wishes !!
