Hello Shubhangi,
I hope you are doing well
According to your query, I think you must be talking about the SPPU MSc Virology entrance examination.
If so, after examination the university releases the results in a few days after which the individual departments based on the scores release a merit list along with a waiting list.
Once the merit list is released, the candidates who are shortlisted in the merit are informed and invited to the individual departments for admission process and the admission is confirmed once the admission fees is paid.

Hope this information helps you.
