I thought I'd bring this up because it's a slow week and it was brought to mind by a string on that other board.
I entered ND in 1968 had was required to take two semesters of Calculus as part of Freshman Year of Studies even though I intended to go into a social science. Back in First Grade, I was nearly held back because of my weaknesses in arithmetic. The Calc teacher stunk, I was completely, and I mean completely, lost, there was no tutoring help, and when I took the final exam first semester I just signed my name and handed it in. I got an F and had to re-take the semester. I got a D the second time. By then I was an emotional wreck. Sophomore year, they put me into remedial math with others of my ilk, and I proudly pulled a C, so they let me out of math.
I blame Notre Dame and my Catholic Baby Boomer education for being lousy at teaching, not myself for being dumb at math. I still have nightmares about this fifty years later -- they usually involve forgetting that I had signed up for the course until the last couple days of the semester. My GPA never recovered from the F, D and C. You can see that this still bothers me. I've never needed Calculus one bit since then and have had a successful career as a city planning consultant. They told me that the rigor of Calculus would be good for me. F you, Isaac Newton.
I was heartened to read on that other board that many others at ND, even many years later, and even those in aiming for engineering or science who had Calc in high school, had similar stories.
'Nuf of that. Beat the Trogans.
