To take the IELTS test, there are no specified educational requirements. However, note that you must possess an extraordinary command of the English language to pass the test. You might need special coaching for writing, listening, reading, and writing sections of the IELTS Academic or General Training test, depending on your choice.
In short, you must obtain the minimum IELTS scores set by the university or professional organization. Apart from that, your IELTS scores alone will not determine your acceptance. Universities abroad often set other admission requirements and companies will prioritize the applicant’s work experience other than the IELTS scores.
It is suggested that you score the best you can to enhance your chances of being accepted while applying with the IELTS scores. You can start your application to universities or organizations abroad once the results are out. Your IELTS scores are valid for up to 2 years from the date of results
