ElSupremo,
It really depends on the individuals skills... I done Law at University because my skills weren't that great in Maths or Physics (even though I got my Highers in both subjects)
Some people will find it easier than others, for example those who studied advanced maths/physics or those who have worked as engineers in various industries.
The thing a degree does is prepare you for the level of work you will need to put into your course. You will know how to study, how to manage your time and understand the quickest and easiest ways of learning things (you have been studying for 4+ years, you must have mastered it by now! :P )
A degree is good to have regardless of what career your going into, as they are a clear example of determination in a particular area they can also be used as a back up incase you don't get the dream airline job you have been chasing.
However, if an airline believes someone is a better pilot than yourself they will easily pick the skills over the degree.
