Hello

You have not mentioned the name of the programme for which you had not applied for "multiple choices" hence I am assuming you were talking about NPAT. The registrations began for NMIMS NPAT in the second week of december 2020 and is to continue till last week of April 2021.You can change the choices during form correction after a week when the application window for the NPAT exam closes.  For more details you can click on https://bschool.careers360.com/articles/npat-bba-application-form
