Sacy, your medical license is the permission or rather power for you to practise medicine. Your EWS reservation is the benefit that the Government has given you to get to the path of being able to gift yourself a medical license post completion of MBBS along with your 1 year mandatory internship. Both of them are different. And your private license will have your name, Regd no# and may be other details but certainly not your reservation or Category details. So do not worry about it.
