Sudarshan, EWS reservation is for those Candidates who belong to Gneral Category but have annual income less than 8 lakhs from all sources. But SEBC is a reservation for those Candidates who belong to BC Category and are socially and economically backward. You cannot be eligible for both EWS and SEBC at the same time because both of them are completely for 2 different CAtegories. Now, if you fill in EWS as your Category while filling the application form, because you will not have the required documents, you might lose out on your admission due to incomplete document verification. So you should select OBC-NCL in NEET application form and then select SEBC in Maharashtra State NEET counselling.
