Good Afternoon,

hoping you are doing good, as per your query first you have to give the Chandigarh University entrance exam (CUCET) it probably starts after JEE main exam, you can consider the opening timing for 1st year student after JEE main 2022 exam. In my case I gave my CUCET exam on 28th September 2021 and my class were start from 2nd October 2021.
