i mailed the adcom but got a generic reply, stating whatever is already mentioned on their website
At the discretion of the Admissions Committee, the requirement to provide English language test scores may be waived. You can apply for a waiver if you have completed, or are currently completing one of the following:
A degree-level course that is:
full-time
at least nine months in duration
undertaken at a recognised institution where teaching and assessment throughout the course is undertaken entirely in English; and
has been completed within 2 years of the start date of the course to which you are applying.
You can also apply for a waiver based on substantial professional experience if:
you have worked for a minimum of two years in a majority English speaking country where the main language for the role was English
your role involved daily professional use of each of the four language components (reading, writing, listening, and speaking)
you worked in an appropriately technical context to demonstrate the ability to communicate effectively in an academic environment; and
your role has ended no more than two years before the start date of the course to which you are applying.
If you meet either criteria based on your previous education or your professional experience, you will need to indicate this by answering yes or no to the English Language waiver questions on the ’English Ability’ tab on your application form. If you choose the professional experience option, you will need to summarise your role and use of English to enable the assessors to judge whether it meets the criteria.
i am not able to comprehend their advise on following statement
"has been completed within 2 years of the start date of the course to which you are applying"
