SAT

Hi Viren Singh,
You don't have to take GRE and SAT at the same time because SAT is for UG course and GRE is for PG programs, these tests are mainly for USA. So, first you decide what to study and then appear for the exam.

Dear,
The SAT score eligibility varies from university to university. An ideal new SAT score in my view is 1200+ (higher the score, better it is) and with this score, you may target good universities in the US. As for TOEFL, it is more of an English assessment test rather than a competitive test. An ideal score for a UG course would be 80+ in TOEFL with no individual band less than 20. I'm not sure what you meant by "direct admission" and therefore cannot comment on the same.
Hope this helps.

Hi,
Yes, but the university will eventually check your 12th percentage also when making a decision. You can check this website, it mentions the college names and scholarship amount for specific SAT scores. Please browse through the website given:

Hi Nitin,
It is possible to take your SAT but it makes no sense taking the SAT since you won't be eligible to apply for any universities without passing class 12th.

Hi Nitin, very easily. SAT can be taken though 10th till 12th. But ideally it is suitable if you are in 11th or 12th to cover the SAT syllabus properly.
