Part time/summer work is possible. Be prepared to work the graveyard shift if not in an office based role. If your studying for a degree it sounds like you have age on your side and should not rush into flight training. A couple of years of work experience (in any industry) will help prepare you for the demands of the training course/job. In my experience, people who come direct from school or uni have to develop certain skills while on the course, which can add extra pressure.
