Last summer, I went to the University of Southampton, and they told me that degrees are slightly easier than A-levels
The reason being is that the difference between A-levels and degrees is that during a degree, you have a lot less help from teachers reminding you of deadlines, homework, etc. The hardest part about a degree is adapting to this dramatic change in learning and support.
if you can cope with that, the university told me, you will often find a degree easier (and more fun) than A-levels, although it does depend on the subject you are planning to study at degree level...
