Brand Management is mostly a subject in MBA else a graudation or post-graduation degree.Howerver,there are very few colleges which provide diploma in Brand Management post 10th.

One such is Amity online diploma course on "Diploma in Advertising and Brand Management(DAMB)".Please find attached the link for reference: https://amityonline.com/AllProgramEligibilityCriteria.aspx?ProgID=QvG+ZQ+nJn5WqiyXey0O6g==
