I am an Engineer with two years work experience. I have good academic scores as of now. I am starting my MBA in Marketing (2015-17) from IMT Ghaziabad, India.
I wish to do PhD in future after two years more of work experience after completing my MBA. I would need a good GMAT score to get into some of the top universities around the globe.
1) I wish to know whether it is appropriate to take the GMAT now (when I am fresh with all the quant and verbal concepts) and apply using that score in year 2020 (given GMAT is valid for 5 years, isn't it?)
2) Also, what all things should I take care of during my MBA and in job so as to be a competitive PhD applicant.
3) Are Indian universities like ISB good for PhD? What other Indian universities are good for PhD?
4) How much tuition fees one can expect while doing Phd (for good bschool in US, Europe and Singapore)?
