Hey Ritesh.
No, CLAT is not compulsory to take admission in Chandigarh University. CLAT is a common entrance test for admission in National Law Universities only. Some private institutes may consider your CLAT rank for admission but it isn't compulsory.
For admission in CU your marks qualifying exam like 12th boards or equivalent or marks in CUSAT or both are considerd.
