Welcome to ISC! Please submit this query in our Ask Expert section 's category of Indian Education Consultants for detailed guidance. I suggest that, when posting the query there, you could mention which field you have graduated in and what are your interests for which you are keen on doing a short-term course. This would enable ISC members to guide you better.
