I have received a Conditional Offer Letter from WARWICK UNIVERSITY and they have asked me for the result of English proficiency. I mean, I got 55 percent in 12th and my 5 year law education is in English and I got 60 percent, so how can I get ilets waiver in such a condion.
And yes, I saw a video on you tube yesterday, in which the student gave essay writing and she got an exemption. Guide me on whether I can do something like this or how I can take ielts waiver.

You can ask the uni via a mail or simply check if they accept Duolingo English test, which is much cheaper and faster.
