The course is a great way to learn English.  It can prepare you for formal exams (such as IELTS, TOEFL) which are often required by universities and governments.  However, specific requirements vary widely and we would advise you to check with the relevant university or government directly to find out what is required. Our certificates are proof of completion and that you passed the test for each module. You will likely have to take individual tests every time you apply for entry to somewhere.
