Masters

Yes, check in US universities since they are very flexible.

Hi, it depends from university to university,but generally you must have a first class and must have a valid IELTS score.Highly ranked universities require more than 75%.

Hi Sam, you can study MS Management or MS International Business Management/Global Business, Human Resources Management, Entrepreneurship etc.

Hello Sunil,
PG diploma indicates that it is "Post Graduate" diploma. Meaning you can do it only after obtaining graduation. Unfortunately two years if study for diploma or even obtaining this diploma is not equivalent to degree and hence unfortunately you are not eligible.

Apart from IITs and NITs, there are many other reputed Universities for chemical engineering.
As you wish to do Ph.D, I hope the following list of colleges would provide you a better base:
1) BITS Pilani
2) Delhi Technological University
3) Anna University, Chennai.
4) BITS Mesra
5) Jadavpur University, Kolkata
6) Thapar University, Patiala
7) Institute of Chemical Technology (ICT) Mumbai
8) JNTU, Hyderabad
9) SRM University, Kattangulathur Campus
10) Ssn College Of Engineering, Chennai
11) Manipal Institute of Technology, Manipal

Sorry. A diploma holder is not eligible to do master/post graduation courses unless he or she completes a degree course. You can go for degree/post diploma or short term courses.
All the best.

If you are interested in MBA IT or M.Tech IT, then go and pursue it, but only from IIMs or IITs, after that your lifestyle, pay scale, career will be top position. Else, stay in job for at least two years and prepare CAT or GATE side by side.

According to me, you need 6.5 or 7 bands for pursuing Masters in Canada.
