For the electrical systems major, is it recommended you take real analysis then complex or is Eng maths enough?
For electrical engineering, you don't really need Real or Complex Analysis. Those subjects are more on the side of
pure math, meaning you'll be diving really deep into math, and examine proofs and how the nitty-gritty of calculus works

They're great subjects to train your mathematical thinking ability which is undoubtedly useful for an engineer, but the concepts learned aren't that directly related to engineering. It has definitely sharpened my mind and helped heaps doing my physics major.
If you're more interested in the practicality of applied math rather than pure math, I'd recommend looking into Discrete Math, Differential Equations, or Probability and Statistics
