Hello, there is no eligibility for SAT. Students are normally in the age group of 17 to 18 as the test is taken by high school students. Your preparation will.depend on your own level of competencies, prepare a study chart, take practice tests or mock tests regularly, online materials are also available please keep referring to those and if required take an additional coaching class. Keep reading a lot of English novels and news and learn new words, this will help in the verbal section.Practice is the key.
Regards

SAT is not mandatory. But if your grades are average it is recommended you take SAT as universities in Canada are very competitive.
