Okay, so I did my aero degree 30 years ago but I suspect that not much has changed. Some universities (Bristol, Imperial, Oxbridge) offered an aeros degree that was really a fluid mechanics degree with nothing but hard sums. Others (Soton, City and Loughborough) were much more practical (still lots of hard sums tho') with third year options on aerospace design and management etc. You've got to go into it with your eyes open - that's what prospectuses (prospecti?), open days and interviews are for. Spitfire Retreat is right, if you want to spend 3 years navel-gazing then do soc-sci or some other pansy subject, if you want a challenging but rewarding 3 years with the prospect of well paid (?) and interesting employment at the end then knuckle-down and do a proper engineering degree.
