This line here in that awful post
so she wants her phone setting up for her so it 'DOESN'T USE MY INTERNET'??? Erm, Lydia, you do know that internet usage isn't pay-per-minute don't you? What a bizarre thing to say!
Back to the subject of her qualifications - here in the UK we don't 'graduate' as such. You take GCSEs age 16 at the end of high school and you either pass them all, fail them all, pass some, fail some. Good grades were classed as A - C and even though D and below are still 'passes', in reality, colleges, Unis and employers want C or above to class as a pass. Then we usually go on to either a school 6th form or a college to take A-Levels or NVQs, that type of thing, between the age of 16-18. After that, you can go to Uni.
The uni you go to depends on the A-Level results you get. There are some Uni's that are very popular with popular courses where by you will need good GCSE and top A-level results to get on the course. At the total opposite end of the scale, there are Uni's that are desperate for students to attend and so you can often get on courses with very poor qualifications.
Lydia left with no GCSEs (and obviously she didn't go on to take A-Levels) then her work experience in that topic field, would be the only thing she could use to apply. If that particular Uni were low on numbers that year and accepting students with poor qualifications, then this is how she would have been able to get on the course without GCSEs or A-Levels.
