I often come across many people wondering which IELTS test they need to take. Firstly, all IELTS test takers should understand the 2 IELTS test types - Academic and General.
Generally, IELTS Academic is taken by students who want to move abroad to pursue their higher education.
IELTS General is taken by people who want to migrate abroad and get their permanent residence (PR). It is generally accepted in countries such as Canada and Australia.
IELTS is a pretty expensive exam and it is extremely important to know which type of exam you should give depending on your plans. Therefore, do your research before you book for your IELTS exam. Visit the website of the college you're applying to or the country that you wish to migrate to. Don't end up wasting money and effort by choosing the wrong exam.
All the best!
