As an EE student nearing a bachelor's, I haven't seen all that much use for more abstract mathematical topics in my classes. I would say it is much more important to be very comfortable with the more basic, concrete topics that will show up all the time: algebra, ODEs and PDEs, (vector) calculus, Fourier/Laplace transforms, linear algebra, probability. An EE specializing in the physics side of things may wind up using abstract algebra or other higher math, but that is a pretty small percentage of engineers.
