Dear Sneha,

The undergraduate program admission in USA, Canada and a few other countries require SAT examination. Admission to admission to others require a direct application and some may require an additional test. Almost all universities require some kind of scholarship, either need-based or merit-based. 

Do tell me more about your academic background for me to be able to suggest you better. Specifics like what are you pursuing currently, what was your last CGPA, and expected CGPA etc.

DO revert if you need more information.

All the best!
