For my first two years of EE coursework, I'd say 90% of the math can be straight up solved with algebra, or simplified to a first order differential equation. Engineering is not about calculating hard math, it's about knowing when to apply which techniques.
Uh. Best tip I can give you is learn to be fast with your calculator; it'll save you a lot of time. My personal favourite is Sharp EL-W535XBSL. This underrated $20 tier of calculator lets you convert between polar/rectangular coordinates, basic matrices up to 4x4, binary/hex calculations, unit conversions, and all your basic trig functions. And you're not lugging around that $90 TI brick that's banned from exams anyway.
Ohyeah. One of my profs made the circuits to water pipes analogy. Learn those, they're fun and helpful.
I love my Sharp EL-W535 Writeview calculator. It's simple but holds the numbers and "looks" like a textbook without the graphing technology.
You can get it here for around $12 https://www.amazon.com/Sharp-EL-W535XBSL-Engineering-Scientific-Calculator/dp/B004J6M29S
Sharp Electronics EL-W535X Writeview. It's approved by the ENCS dept.
