English medium school
If you have studied in a school where all instructions were in English, the admission board in the UK may take this into account as a proof your English level is convincing. That meansIf the students have English as the medium of instruction throughout their academic life and overall good grades, then an admission committee may waive the IELTS requirement.
Conducting a telephone/Skype interview
Some universities may ask you to give an online interview through Skype so they can assess your English level if you have not taken the IELTS and you feel is unnecessary. Usually, they are interviewed over telephone calls which could be at your nearest test center. This interview can determine their English language competence.
Note: If you find a university that waives off the IELTS test, you must ask them hand to you a document that you are eligible to take a visa.
