Agreed. I’m guessing you had one year of chemistry in college. No p-chem. No organic. That’s not even touching any of the graduate level courses in chemistry.
I’m guessing you had one year of physics. There are a ton of higher level physics classes. And even more graduate level physics.
But yeah, you with your one year of each is enough.
Don’t even get me started on math. Guessing you topped out at diffy-q. There are senior level math classes beyond that as well as graduate classes. I had a great grad class in numerical modeling.
