But sitting for some A levels again is a different thing than to be able to state that you graduated from uni X with a degree.

Who said I sat A Levels again?! I said I sat an access course. Which is where you study a variety of topics and modules, centred around your desired uni course (so I sat modules including, but not limited to: English language and literature, writing skills, comms and media and psychology). You sit modules in order to build up university credits which then affords you entry to university to complete a degree.

How you don't know this considering you say you know so much about university teaching is a little strange. But then you also said the DELTA was a 4 week course, so your knowledge of all things academic is not quite as extensive as you'd have us believe, is it?!
