Once upon a time, a very looooooooong time ago, I was the scholastics sergeant for my company. I was also the scholastics corporal and the scholastics officer, which meant I spent 3 years straight doing study checks. Yay.
You would not believe how many engineering majors with ROTC scholarships switch to history majors midway through their freshman year. Or maybe you would, especially if you were either a scholastics officer or an engineering major. I could never figure out why kids who were so smart would suddenly think they could quit studying once they were in college.
