I think those are perhaps the most important things that college teaches, regardless of major. In high school, the answers you need to do well are more or less on the surface. In college, you have to dig, and learning to dig is the key.
Gee, I thought I was an "older" college graduate, but I was only 30, not 50.
I think at my age, 70, I might be able to take classes free. I've thought of taking history classes just to be a pain in the ass in the classes by telling the other students the truth when the instructors are spewing bullshite.
I can’t imagine sitting in a college classroom these days. Where the instructors 25 years ago were dedicated lefties, they weren’t the fire-breathing, openly hostile monsters I’ve heard described lately.
I pity today’s student. If he/she is trying to maintain a high GPA, they have to nod and smile and regurgitate that which the rabid moron spews on a daily basis. They can never show their hand, lest they get a bad grade.
