I'd say the min was a B.S. in a science degree (e.g. engineering, physics, biology, etc....political science is not what I consider a "science")
At many schools (not mine...I was awarded an A.B., econ was one of my majors) economics is a Batchelor of Science program. But yeah fair.
Are we counting psychology...pre-med...the eventual MD...DDS...too? Are we really going to give the same percentage weight to a dentist that we do an astrophysicist?
And are we then going to discriminate by the awarding institution? Does a science degree from Liberty U really count as much (for this purpose) as one from Cal Tech?
