Hi Nikita
Applying for MPT will require lot of research before you zero down any university in Canada as an international applicant. I am sharing the requirements of one of the best universities UBC. Take a look and prepare all your documents and certificates. You also require some work experience.

Hi Parikshit,
The courses for international students are mostly A level programs (equivalent to higher secondary) leading to progression to UG program. Also, you wont get lot many options to apply after 10th. I recommend you clear your 10+2 exams and then apply for UG programs. This way you will save a good amount funds too.

Dear Jewel, If you cannot go out, you may refer to ETS.org as that is an official site for TOEFL prep & has sample questions in it. Also you may buy a book from ETS which comes with a CD & since its an online test you may practice it from anywhere.

GRE is one of the standardized test used by mainly non-business institutes earlier but now its widely accepted for admissions in graduate schools abroad.Its based on analytical and verbal reasoning.
While TOEFL is english proficiency test to be taken at all levels by students seeking admission abroad so generally you take both.
Hope this clarifies your doubt.
