You click on 'Am i eligible' and it bring up a page that gives a list of colleges. Being in the U.K i click on the 'Going to university/college in the UK?' link. Then click on the 'Am i eligible' again which states -
If you are a student, you must be enrolled in an education institution geographically located in the United Kingdom, Jersey, Guernsey or the Isle of Man. If a Higher Education student, you must be enrolled in an undergraduate or postgraduate level course. If a Further Education student, you must have at least 15 hours of scheduled contact time per week for your course.
I have a 'ac.uk' account, but do less than 15 hours.
You dont have .edu email in England (thats probably why i ignored it)
