I never really understood the part of going to university if you want a career in aviation
Because a career in aviation can be destroyed in the blink of an eye if for any reason you can't get a Class 1 medical. Then having the option of another career can be a life saver.
If you don't want to do law, take a year out, and reapply for something you do want to do. But to get any sort of decent job these days a degree is pretty much mandatory (and ubiquitous).
