Do I need to take the recommended course in order to gain more ad opportunity?

I will be applying as an international student.
Thank you for the suggestion. I will take discrete math, cause if I get rejected I will think why I didn’t take it?
I will also have Linear Algebra, Computer Organization, University Physics Laboratory I, University Physics Laboratory II, American Literature II next semester. Literature is in winter so it’s ok to keep it, I’m thinking if I need University Physics Laboratory II.
