Hi,
IELTS is an offline test and not a computer based test. For the speaking section there will be a face to face discussion with another person.

Hi,
Only IELTS score is not sufficient. You have to see if your academic grades are upto the mark and if you meet the admission requirements of the colleges. Please decide what to study also and accordingly check on the university/college websites.

Dear,
Your IELTS score is nothing to do with your visa fees. IELTS exam is just to check out your proficiency level in English. However, you can get some sort of scholarship with this score, but don't ever think of any relaxation in visa fees.
All your visa proceeding is been done by the Embassy (of the concerned nation), so they have their own criteria. IELTS is taken for admission in a university.
Good wishes.

If you really want to get 7 or more bands then you have to take at least one listening test a day. Simply complete IELTS booklet and up to ten reading tests from the websites before your final test.
God bless.

McGill University is a good option for you based on the QS ranking.

Yes, you must take the TOEFL or IELTS. You must also submit a very good SOP/CV/resume too.

Hi,
This is perhaps the best time. Try to take the test by Sept. If you are planning to study abroad then you must submit your applications by Oct/Nov depending on the university or country you are applying to.
