It is  possible that you might still be able to apply for admission to the Faculty of Commerce at MSU Vadodara with your OBC certificate, even without a non-creamy layer (NCL) certificate at this time.

Check the Faculty of Commerce website for admission guidelines or FAQs. They might have information on the NCL certificate requirement and the process for submitting it later.

Call or email the Faculty of Commerce admissions office. They can provide the most up-to-date information on the NCL certificate requirement for OBC candidates and the procedure for submitting it later if allowed.
