Sir please some one guide me to do my MS in abroad...
IS there any entrance exam for doing MS in abroad?

Where do you live now? Do you have grad schools in mind?

Depends on the school you might want to go to. You will need to get a Visa most likely, depending on the country. In the USA, you need a GRE.

For US GRE and IELTS required for admission
For Uk IELTS required
List out universities you want to study and follow the requirements for admission or better any abroad consultant
