ews qoata available in mumbai medical colleges
Yes, definitely! See the central government of India has made it mandatory for all the engineering and medical colleges (government) to have a 10% quota for the Economically Weaker Sections of the society, which is the EWS quota. So, as a result, all the government medical colleges of Mumba have EWS quota for such students and you can take it's benefit.
Hope I have answered your question. All the best!
