That sounds about right...I have a BS in Chemistry, and taking Physical Chemistry was at the extreme margins of what I was capable of understanding...that was hard enough for me.
I have never, ever understood this concept of trying to push women (or anyone else) into the STEM fields. Why? Just to have them there? They make a big deal about women being underrepresented because they are “discouraged” from entering those fields, but when I was in school decades ago, I didn’t see any discouragement going on.
I think there are many people who want to see something a certain way, so they use pretzel logic to make it “true” in their heads.
Those are not people I want engaged in “science”.
If you are a Chemical Engineer and you get the temperature/pressure controls set wrong, the plant blows up. It doesn’t take into account your age, sexual orientaion, gender, gender identity or skin color. It still blows up just the same.
