This mostly relates to Student Finance and accommodation.
At some universities like Manchester University, during your undergraduate degree, you can stay in University accommodation all year round. But at the end of your third year, if you decide to do a masters' degree at Manchester (ie the same university) immediately after and you get an offer, would you likely be able to continue to stay in accommodation over the holidays after undergraduate accommodation and be seen as still being a Manchester student in the interim between graduating undergraduate and beginning postgraduate?
