Do a degree in something that gives you a lifeboat.
Law, Finance etc.
Wouldn’t bother with an aviation degree. Too many eggs in one basket.
Do a real degree and your ATPL subjects at the same time. When you are in study mode they are no more than first year undergraduate level in science or engineering.
I did a Degree and flew on the weekend. Pretty busy couple of years but it paid off.
Bottom line ; you either love flying or you don’t.
