Mumbai University — PRN number profile unlock

Address:

Mumbai

I have registered myself on mumbai univeristy website in the year 2021 and taken admission in royal college for BSc Chem bot zoo but ended up cancelling my admission because i wanted to change my course to BSc micro biology in the same college or BSc Biotechnology in another college (Thakur College) so i had to cancel my admission and take a gap year. This year in 2022, i want to take admission again so what is the procedure for this? Can i register myself again on the mumbai university website and fill the form again and get another PRN Number because my existing PRN Number profile is locked as i had filled the form last year and can't make any changes. Pls help.
