Calc III vs DiffEq?

So, this year I independent studied Calc BC (with help from a teacher) and I’m taking the exam on Tuesday. I want to go into physics and/or engineering in college, and next year, I have the option of doing Calc III or Differential Equations first semester through dual enrollment. My first choice would be Calc III, but it conflicts with Arabic III (I really enjoy Arabic and got an A in 1 and 2, but I already reached French 4 so I don’t have any language requirements), but Differential Equations does not. I know both are advanced classes and would look good, but I was wondering if Calc III would look better, or if I should just take Differential Equations and Arabic.

As an Engineer, I took Calc 1, Calc 2, Multivariable Calc and then Diff Eq.

I don’t think that either would “look better”.You can take Calc 3 in college.
