Don't worry, there might be a solution! Here's how to address the missing category certificate in your PMSSS application form:

Check the PMSSS website or notification:

• First,  refer to the official PMSSS website or notification for any information regarding correction of application details. Some institutions might have a window for rectifying mistakes.

Contact the PMSSS Facilitation Center:

• If the website doesn't offer correction options,  reach out to the PMSSS Facilitation Center. Look for contact details (phone number or email) on the official website. Explain the situation and inquire about the possibility of submitting your category certificate later.

Worst-case scenario:

• If there's no way to submit the certificate later, you might have to wait for the next application cycle. However,  you can still try contacting the Facilitation Center to see if there are any alternative solutions they can offer based on your specific situation.
  
  You can even contact through PMSSS website or PMSSS facilitation centre to address your issue.
  
  I hope this information helps.
