TOEFL

Yes absolutely. You need to work on your SOP, LORs and get some work experience in your field of interest.

Hey Vickey,
TOEFL registration is usually done online through the website www.ets.org/toefl
Kindly, visit this site for exam centers, test dates, etc. TOEFL may be online test or paper based test, the online test is more common.

Hi Ranjeet,
TOEFL or IELTS are part of the admission requirements. Top universities like Harvard, etc. do not require these scores as the applicants themselves are brilliant and do not require additional tests to prove their brilliance. I hope you got my point. Universities may also waive of these requirements depending on the candidate's profile and communication skills. I will recommend you to communicate with the universities before you apply.

Hi Rithick,
Having a good TOEFL score is good, but that alone will not make you eligible for getting any fee concession, apart from having a good test scores, the university will consider your overall profile including but not limited to good statement of purpose, letter of recommendations and your academics as well, make a strong profile to first get admission and then check out fee concession.

The application process should start a year before the planned intake. You must finish the application submission by 2017 latest by December, 2017 depending on university websites. The admission windows will open after July/August 2017. You must keep checking university websites for updates.
You can take SAT and TOEFL either during class 11th or before your boards. It shouldn't hamper your board exams, so schedule wisely. You can also apply to colleges, while in the final semester.

You must take both. Both are different tests, TOEFL is for English language proficiency and GMAT for aptitude in reasoning, quants, etc. Many universities also accept GRE instead of GMAT. You can check university's websites for scholarship exam, most universities do not have any separate exam and all applications are automatically considered for scholarships when you apply.

To get admission in foreign university, you need to write language proficiency exam, TOFEL.

Majority of colleges ask for TOEFL or IELTS scores for the colleges which accept GMAT abroad.
