Ramesh, you have enough work experience for a serious, internationally accredited MBA. Why go to Heriot Watt, which is certainly a okay, middle-of-the-road unaccredited MBA, when you could do n excellent one with AMBA accreditation?

Indeed, you should check out schools that have either AACSB, AMBA, or EQUIS accreditation in order to ensure a decent learning experience and good placement possibilities afterwards. If you can work for another half year and build your work experience to three years, and score 610-650 on your GMAT, I'd suggest these in Scotland:

University of Edinburgh Business School
University of Strathclyde
Aberdeen Business School

Although Aberdeen does not require you to take a GMAT, I would, in order to apply to the others and hedge your bets. Also, it demonstrates quantitative skills, something that Aberdeen would look for anyway.

Aberdeen Business School is now accepting students with no work experience (mainly students from engineering background). Due to this most of the students in Aberdeen are with no or 1 year work experience.
