Hello Bhanu,
Hope you are doing well.
IELTSis an English language exam that is required to be taken by international candidates considering studying or working in a country where English is the main language of communication. Most popular countries where IELTS is accepted for university admissions are the UK,Australia,New Zealand,USA, andCanada. The exam mainly measures the ability of test-takers to communicate in the four basic English language skills listening, reading, speaking, and writing. IELTS exam is jointly owned and conducted by IDP Education Australia, British Council, and Cambridge English Language Assessment.
IELTS 2019 exam is required for migration as well as academic purpose abroad in English speaking countries like Australia, UK, New Zealand, USA, and Canada. It is the only English Language Test approved by UK Visas and Immigration (UKVI) for visa applicants applying both outside and inside the UK. A lot of students get confused about why are the IELTS scores required. The simple answer to this is that foreign universities and visa granting authorities need to be sure that you will not have communication issues while staying in the country. You need to show agood understanding and strong command of the English language and that is why your overall IELTS scores are so important. Another common doubt students have is whether IELTS is acompulsory exam or not. No, IELTS isnt compulsory in all university admissions. Many universities might not even require IELTS scores for admission purposes. But remember that if you dont give IELTS, your chances of getting the student visa might suffer as the visa officers may not be convinced about your English proficiency without IELTS scores. So it is safer to appear for IELTS and aim to score at least 6 bands overall.

You can take the IELTS exam with the British Council or IDP up to once a week (four times a month). The British Council and IDP global schedule for test datesare 48 days per year.

IELTS Eligibility:
IELTS can be taken by anyone irrespective of age, gender, race, nationality or religion, however, the IELTS test is not recommended for those under 16 years of age.
Hope this will help you.
Good luck
