uni and HE college,Watch
HE colleges offering degree level courses will have those courses (Foundation years or full degrees) actually certified by a University. They are not 'degree awarding' themselves. You wont 'go' to the awarding Uni for classes - and you wont get the same level of teaching or the same student experience.
Some Unis offer Foundation courses etc at local HE colleges that then lead to an 'on campus' full degree at their Uni - they just 'farm out' the Foundation year to a local college. The advantage is that 'locality' means that they are able to offer degree level courses to those for whom 'going to Uni' might be impractical (those with families), or who can meet the lower grade requirements of an HE college and not that of the local Uni.
What course are you looking at, and which subject?
