Just a point about (British University) degrees here:
Foundation degree = 1 year full time study (normally), equivalent to 2-3 A levels. It is a degree in name only, no employer regards it as such.
Bachelors degree = 3 years full time study, after A levels or a Foundation degree. In the UK these are usually honours degrees.
Masters degree = 1 years full time study, after a Bachelors degree - or occasionally and exceptionally for a very experienced professional who gets exempted the Bachelors requirement.
To refer to "topping up whilst working" is perhaps a bit optimistic for most people.
