SAT

Dear Sambid,
You must have the basic education to be eligible for higher studies hence the 10th boards . Competitive exams are required to shortlist the best students and to check if the student has or will have the ability to bear the program rigour abroad. Having 90% and still taking SAT indicates an umbiased or impartial platform. Regardless your grades you must take the SAT. Exams like SAT not only judges the intellectual value but also helps the university decide which program or areas a student fits the most. Students as young as you most of the times cannot figure out what to study and that's where SAT helps.
Best wishes

Dear Hritik
You may join some coaching in your city to prepare well for SAT as they train you in depth. For indian students verbal section is more challenging. Also,the SAT from may,16 has changed so u will need guidance to score high.

At least one hour a day as per your convenience.

Hi
Akshat
Its so good to see you planning at the right time. If you are planning for MIT, start creating an excellent profile by participating in science projects, Olympiads and other co curricular activities as they look for an all rounder. To prepare for SAT or ACT you must take coaching as they train you on certain tricks n tips to perform better. In addition to this, community services is also essential. But keep academics on the top.

Quant and Verbal.

Dear Aagam,
SAT can be taken only, if you are an international student. You must now take the Aptitude Test (AT) to be conducted by the institute. Please check the institute webpage for details.
