Hii!
Your question is quiet unclear. It would be helpful for us to provide you with the accurate information if you mention the name of the College/ University properly with the location it is situated in.
Also, mention the course you want to pursue there.
If you are talking about TNDALU 2020 admissions, then the admission process will tentatively start in 4th week of July, 2020.
You can also visit the respective College' official website and get the updates.
Hope you understand.
Good luck!
