Make sure you understand how to meet the English Language requirement before making your application. You must have either (1) passed a recognised English Language test at level B1 (intermediate); (2) have a degree that was taught or researched in English or (3) demonstrate that you are a citizen of a majority English speaking country who does not need to satisfy this requirement.
If required, you should book an English language test before you reach the qualifying period, so as not to delay your application. If you have a degree taught in English which is from an overseas university, you will need a copy of your degree certificate and a letter from Ecctis confirming your degree is equivalent to a UK qualification and that it was taught in English. You should obtain these documents as soon as possible.
