SAT

Hi Debasmith,
I do not understand the part "correspondence to SAT". SAT is mandatory and so are good marks. Also, the universities in USA will see your overall profile and not just your marks. Nevertheless with regards to your query you should aim for a first class, 70% and above is good. The more your percentage is the better. SAT score to be aimed is above 1400.

SAT scores are considered for scholarships. However, 100% scholarships are not possible.

Hi Guneet,
SAT is an essential part of the US college admission process. Very few colleges have SAT as optional requirement but if you don't give SAT you have to submit something else in place of SAT such as Andhra Pradesh scores, IB Diploma, etc. and you must have an exceptional profile. This also becomes difficult for international students. You have to check college websites and enquire. Some colleges having SAT has optional are Hofstra University, Smith College, Pitzer College, etc. You have to do your own research and find out the requirements.

Best wishes.

It depends on the university and the country in which you are going. Some ask for both the scores, some only require SAT and an English language eligibility test.

Best place is the official website of the universities to which you want to apply. Read the information given on it about admission, scholarship, and application. Where you want to study and when?
