So how long have you been on the degree?
If its a year, or even months, then i would throw in the towl now and think long and hard about what you want, and what you want to do.
If you desire to be an aircraft engineer and want to go to uni, do a foundation degree for two years and then get a job and do the (Hons)Bsc part time over a few years.
A fair few places do this now, i know Bristol College and Kingston Uni do. They work close with BA and KLM and i think employment rates are good from what i can make out talking to lecturers.
I started a AeroMech Degree, i didnt really know what i wanted to do, so i swapped to MechEng and now have much broader options inc aerospace once i graduate.
