New Zealand

Hi,
Chances are low if you have less than 50%. No foreign university actually prefers such low grades. Talking about NZ they have higher requirements so less chance. You can check countries which are not too tight with admission requirements like Finland, Ireland, Russia, Turkey, etc.

Ideally, they ask for 70% and above. However, it depends on the institute. You need a minimum of 3 to 4 years of experience (post qualification) for many post-graduate programmes including MBA and engineering.

Hi,
Canada has more options though both the countries are good.

USA is the best for computer science engineering.

None of the country offer guaranteed job unless you do it from a well-ranked institute each country is good in its own term.

Hi Dhruv, its a difficult question to answer since every person has his or her own interests and skills. Science itself is a vast topic. What subject or branch in Science are you interested in? Please be more specific with your requirements so that we can guide you in a better way.
