Unless you want to do it mainly as a hobby, I'd really suggest start going to school as soon as you can and take it one set of courses at a time. It's highly difficult to find work as an EE if you do not have an ABET-accredited college degree. It'll be tough to break into the industry without a degree, that was true before then and in this job market especially true now. That's because a company doesn't want to make themselves liable by hiring an engineer with no formal credential.
When in school, make sure to get a good understanding of each semesters' courses as the next will build on it. You can't shortcut the process so prepare for the grind. It'll take years to earn the title of engineer and years to build that knowledge. If your pre-Algebra is weak, your Algebra will be weak. If your Geometry is weak then your Trig will be weak. If both of those are weak, your Calculus and Physics will be weak, etc. EE is one of the heaviest math fields out there so make sure the math knowledge is comfortable. You'll definitely be making use of everything you learn in a standard pre-calc book: trig, complex numbers, secants/tangent lines, etc. However, the Algebra I, II and courses specifically about Trig go into the material deeper (and will provide more practice). Later on you'll see how it all relates and has useful applications (like Euler's Formula).
I'm finishing up a degree in EE right now because I truly found what I wanted to do while working in full stack software. The last time I studied Physics and Math was back around 2011. I'm really fortunate that I took those subjects very seriously from day 1 and tried to learn everything about them, how each piece of knowledge relates to one another and studied to make sure the material is 2nd nature and intuitive to me. Going back to school over 10 years later and I remember so much of this stuff because I really took time to understand it and make it intuitive the first time rather than just memorizing things to pass an exam. Yes, anybody can learn subjects to that extent by simply making the decision to go the extra mile day after day. It sounds like a lot, but the nice thing about Math is when a concept is understood the details don't have to be memorized as they can be derived from the understanding (some memorization is needed, don't get me wrong). Do all your homework, not to earn marks but to check for understanding.
That's so true for any STEM field.
You don't got to be an A student, but really make sure you understand the critical information and fundamentals of each course good enough. You're only cheating yourself if you don't. At the end of each course look back and make sure you walk away knowing the main points. Use all resources available - text books, professors/staff, tutors, Youtube, Khan Academy, Google, classmates, ChatGPT to help with explanations (the newer generations of A.I tools for education will probably be insane), etc. to get to that point. When you see a problem that's tough, break it down into it's components and see if you understand each component and that component's subcomponents. If not, that's an opportunity to go back and make the information concrete and intuitive. Do extra problems. Speaking of which these are highly useful tools for circuits:

autoCircuits (will generate random circuits and answers)
If you want to get ahead, look at the very first math course you're going to take and get a grasp on that before you start taking courses. If it's basic math/pre-algebra don't be discouraged, everybody got to start somewhere. I started college in Algebra I and now I'm completing Upper Division EE courses. I might sound like a lot, and it is, but it's not about how smart anyone is as it's completely doable for the average person as long as they're dedicated. In the past people got it done with so fewer resources, it's exponentially easier today. Like I said, take it one step at a time rather than firehose everything. It's an enormous field but don't get overwhelmed, start small and focused and maintain that scope each semester - the knowledge will build from there.
If for purely hobby and you just want to setup a lab at your place, I found this recently and thought it looked very cool:
InventrKits – Make Something Meaningful. Then go from there. Your focus should really be on Math though if you want to finish college. Very few Electrical Engineering majors don't even touch their first piece of hardware until their Junior year of college. It won't hurt to get ahead, but not at the expense of ignoring the Math foundation.
Best of luck breh!
