It is understandable that you are concerned about applying as EWS while being an open category student (Maratha) in the CET form for MBA 2023-24, considering the Maharashtra government's stance on EWS certificates for Maratha students.

The most reliable source of information in this situation is the admissions authority responsible for the MBA program you applied to. Look for their contact information (phone number or email address) on the official website of the institute or university conducting the MBA program.

• Explain your situation clearly. Mention that you are an open category student (Maratha) but mistakenly applied as EWS in the CET form.
  
  

• Inquire if this will cause any problems during admission processing, given the state government's policy.
  
  There is a chance they might allow you to rectify your application category from EWS to open (Maratha) before the admission process goes any further.
  
  The admissions authority might ask you to submit a letter explaining the error and your ineligibility for EWS due to the state government policy. They might have a specific format for this letter, so be sure to ask about it.
  
  It is important to address this issue proactively to avoid any delays in your admission process. The sooner you contact the admissions authority, the better.
