Hello, I am a rising sophomore in Astronomy and Physics. I am taking complex variables next semester and was wondering the effort required to succeed in the class. There are some other classes I'd like to take, however I don't want to overload myself. I have taken up through multivariable calc, diff eq, and linear algebra at this point. How does complex variables compare to those courses as far as time required goes? As a side note, other than complex variables I am taking Thermo/Waves, computational physics, and an intro to proofs class.
