I understand that, and that it's from your personal experience so I'm definitely not trying to minimise or invalidate your experience.

However I feel obligated to ask if that was a business econ or scientific economics course. My Macro 1 and Micro 1 courses were brutal in the first year. The math was not easy. So much so that about 20% only passed the first year macro 1 course, we had to start a petition to adjust people's grades because of how brutal that pass rate had been...

I'm not saying you're wrong, I'm saying you might be thinking of a different discipline.

Business Econ is a joke, it is where people go if they want managerial skills and to enter the rat race. Econ as a science is all about policymaking, behavioural economics empirical studies, data science methods, econometrics, maximisation and minimisation... Even linear algebra was included.
