I put off taking a science class until my senior year. I took the professor aside the first day and told him I was graduating with a business degree and would never need geology in my life. Unfortunately that guy was not as nice as your professor. I had to take a test from he!!, a long table lined with rocks. I had to name each rock, and write the composition of each one. The earthquakes and volcanoes I did a little better on, but I passed!
I love rocks. But my description of them is pretty pink or purple, shiny, round...you get the message. Soon as I took that test all was forgotten. And I never needed that knowledge to produce financial statements, stock investments, or do taxes.
