The IELTS exam is a highly professional and benchmarking exam jointly prepared and administered by the British Council, IDP Education, and Cambridge Assessment English, and is officially recognized and accepted for applications by more than 10,000 universities and organizations in more than 100 countries.
The IELTS test may be necessary for many reasons. The three most important of these are studying abroad, submitting an immigration application and using it in business life.
Apart from these three reasons, it is possible to take the IELTS exam in order to present it in visa applications, license and certificate applications, especially in England, Canada, Australia and New Zealand, or just to learn your personal foreign language level.
