Hello Prashant. Thanks for contacting Careers360 and we hope we will be able to answer your query. 

Note that the prime requirement for admission abroad is to write the SAT Subject tests. Generally, reputed institutes abroad, look at your:

• Physics;
• Chemistry; and
• Mathematics-2 scores

before making a further decision, irrespective of the course the student wishes to study.

For more information about this important decision of yours, I would like to direct your attention to this Quora question:

After preparing for the SAT, you are required to pay a certain set amount by visiting the official SAT website:

To be frank, it is now too late as admissions to colleges would have already closed. 

You should have prepared six to eight months in advance. For more information about the application process, I would like to direct your attention to these links:
