I am a 32 year old male human with a lot of extra time on my hands.

If I were to start learning electrical engineering from scratch, what prior knowledge should I have to begin studying very basic concepts in electrical engineer?

Should I start with kinematics and trigonometry? I have no knowledge of calculus, chemistry, or physics. My knowledge of algebra is quite limited beyond computational knowledge: meaning I do not thoroughly understand the theoretical concepts but can solve semi complex equations with polynomials.

I'm trying to prepare for university, what should I be brushing up on or studying at this moment? I have a year to dedicate to this brush up prerequisite period.

I don't care about the degree, I just want to actually understand the material and be a useful big braned human.

Thank yu
