Deeply discounted college degree

[Chris Chesser]

As I'm walking down the hallway at work to start another long shift for mediocre pay, I saw a post that my employer will cover up to 80% of tuition costs should I choose to go back to school. School has never been something I was all that interested in, but money is, so if I can get through school for cheap and land a better paying job, it's worth it. 

This made me wonder what all of you in the BP community would do if you had this opportunity at the absolute start of your career in REI. Would you go back to school at an 80% discount? If so, what field would you choose? Highest paying field, or most helpful field for a career in REI.
