Hey! To become a marketing manager, I'd suggest you take up Graduation with Marketing as the special subject. And then do MBA from a good college, again with marketing as the specialisation. For Graduation, I'd say take up B.Com (my 12th standard teacher had given me the same advice, and trust me, he's one of the most knowledgeable persons I've come across so far) - apparently the in the Commerce field, B.Com degree does not focus on any particular specialisation but gives you knowledge about the whole field. Further, for MBA these are the top colleges for Marketing in India https://www.google.com/amp/s/www.shiksha.com/mba/articles/amp/top-10-mba-marketing-colleges-in-india-blogId-6897
