IELTS

Hi Divyanshu, you can appear for either one. Simply check the university website, you will see they will ask for either of these.

Age is usually not a factor while granting visa. You must get admitted to a university in Canada in order to get the visa. You must work on applying to good universities and competing all other formalities, so that your visa application is not rejected.

Most students who are seeking admission in a prominent university in the US, need to take TOEFL or IELTS. However, this requirement can waived if a student produces significant proof about her English proficiency. Usually, students from International Baccalaureate (IB DP) and A levels in India are exempt from this requirement.

Dear Anoj,
Check out Deakin, Wollongong, University of Western Sydney, however if you have any band less than 6 then it may be a bit tough, but nothing is wrong in trying. All the best.

Hello, do you mean admission? You haven't specified your grades firstly. Please be more specific with your question.

Hello,
IELTS is an English language proficiency test. You will be required to take it, if you desire to study or work abroad. Every foreign university accepts IELTS scores.

TOEFL or IELTS exam will help you in getting the student visa, so you must take either of them. Some universities may accept the certificate but it is better to take a standardized test.
