You can probably find some institution somewhere in the world which will give you a degree that is legal according to their local laws for $5 and no time. Is that what you want?
But even cheaper than that in terms of money would be free via a full scholarship, which you can get any many institutions if you're good enough. But then that costs you a lot of time.
And go spend a couple of hundred bucks on Horowitz and Hill (2nd or 3rd Ed.) if you want to learn about analog. That's a good bang for the buck.
In the traditional path, your best bet will be spending your last two years at an abet accredited state school that is teaching focused, not research focused.
An example: this morning I was thinking of a model where I need to open and close a door when a sensor is activated. The simplest way would be for it to pivot on a horizontal axis like an old-school garage door. Now, given a certain weight of door, how do I calculate the amount of torque my motor/drive-train needs in order to open that door?
The average graduate with an EE degree should have no trouble getting the answer in a few minutes: it's basic physics and algebra (maybe calculus if you want precision). But the average person who learned EE from watching YouTube channels probably will have difficulty.
If you are still a high school student, and have a knack for tests, then the PSAT might still the most important test you'll ever take.
20 years ago I was a national merit scholar as a result of the PSAT, and that provided me multiple full-ride scholarship options for engineering.
And yes, it is ridiculous that a computer test you take at 17 can have such a disproportionate outcome, but that was the case, and very well may still be.
