It depends, majors are specific but are still pretty diverse.

For example, I graduated with my bachelors in mathematics and I wasn’t perfect in every class. I struggled with things like Numerical Analysis and other things that were CS-adjacent because programming isn’t my strong suit. Or like how my friend who was studying anthropology struggled in the pure archeology classes because they were more interested in culture and found it so boring. Also people can not do their best the first time around and improve. Failure isn’t the end and that kind of rhetoric creates a lot of unrealistic pressure and anxiety for students. Don’t be rude.
