Dear Student,

As you haven't mentioned any Entrance exam name , so as an average ... I can tell that the demand of B.Tech CSE is higher than any other branches ... you have to score too well to get admission in premium institutes through the Entrance exams .

Well, you can find the previous year's cut offs of CSE in IITs and NITs through the following links:

But.. you need to remember that every  year's cutoff of any entrance exam depends on some following factors :

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

Hope this helps !
