Hi,
If you could state the purpose of taking these tests, it would be easy to guide you because SAT, TOEFL and IELTS are international standardised tests mainly use for the admissions abroad. Whereas, MAT is a national management entrance exam. For the preparation of SAT exam, visit khanacademy.org and the official site for registration is collegeboard.org.
For TOEFL and IELTS, just search on Amazon or Google and you will get e-books to download. I would suggest, you should take a mock test, first and then see which one is easier for you.
All the best.

Hi Sagar Kumar,
PSAT is mainly for high school students in class 11th in US and qualifies them for the National Merit Scholarship. SAT is required to gain admissions in a college and shows college readiness. If you have a good SAT score, you can be considered for scholarships along with admissions.
But, taking PSAT is not for admissions purpose. In terms of format and content there is not much difference, but PSAT is the preliminary SAT and the real SAT is tougher.
