If your EWS (Economically Weaker Section) certificate under the Maratha category has been canceled and you don't currently have a valid EWS certificate, you may face challenges while applying for the MAHADBT scholarship. Here's what you can consider:

1. Check for Updated Guidelines : Before proceeding, check the latest updates from MAHADBT or the concerned authorities regarding the eligibility criteria for scholarships. Sometimes, policies or guidelines are updated to accommodate students in situations like yours.

2. Contact Your College Administration : Reach out to the scholarship or admission cell at your college. They may have specific instructions or alternate solutions for students who were admitted under a now-canceled category.

3. Consult the Scholarship Portal (MAHADBT) : Visit the official MAHADBT portal and see if there's an option to proceed without the EWS certificate. Sometimes, the system may allow you to continue with the application by selecting an alternate category or stating your current situation.

4. Apply Under a Different Category : If you belong to another eligible category (such as open or OBC), you might consider applying under that category if you meet the criteria.

5. Obtain Updated Documentation : If there are provisions for issuing new or alternative certificates, try to get the necessary documentation from the concerned authorities as soon as possible.

6. Seek Legal or Administrative Help : If you're facing significant difficulties, consulting a legal advisor or contacting government help desks might provide a solution or exception in your case.

7. Appeal or Request Extension : If you need more time to resolve the issue, consider appealing to the scholarship authority for an extension or exception, explaining your situation.

Handling this proactively and in consultation with relevant authorities is essential to ensure that your scholarship application is not negatively impacted.
