Hello Aspirant; 

There is no such thing are specified for a particular branch in Chandigarh University. There is not a particular minimum  marks or particular rank are alloted. 

• If there are seats available in CSE after all the candidates have made their selection who are above you in the rank list,  then surely you'd get a seat in CSE. 
• This is required criteria in which the candidates are admitted.

Hope it helps .

Thank you.
