Dear Dhivyasuresh,
Thank you for putting up your query. Seat allotment process starts after the result of 12th and entrance exam are declared. To know the exact date of seat allotment keep visiting the official website of your state board at regular intervals like checking it once everyday. I can't provide the link of the official website as you have not mentioned your respective state board. I advise you to search the official website in https://google.com.
