Hello,

GRE is generally required by universities in North America (the USA and Canada). It can be a mere admission formality or a selection criterion for jobs as well.

• The GRE revised General Test is available at more than 1,000 test centres in more than 160 countries. In most regions of the world, online test is available on a continuous basis throughout the year.
• The validity of score: 5 years after testing year.
• Fee for registering in India is Rs 12,000. You'll require a passport for being eligible for the exam.

TOEFL is a standardised test to judge one's English language abilities.

• Mostly taken by non-native speakers of the language who wish to take admission in foreign universities. A few immigration departments use the score to issue residential and work visas as well.
