Degrees are deeply unimpressive these days
A lot of truth in that. Part-time degrees (such as a Foundation Degree)however have a number of things going for them.
They differentiate you from the crowd because you are working and studying at the same time - no propping up the bar in the Uni most nights.
They are much, much cheaper then full-time degrees.
Recent funding moves now make it possible to pay fees after completion and when you are earning over £xxx.
Most offer a top up route to BSc/BA etc also on a part time basis.
