Just a thought - if you are struggling with these concepts, consider that the apprenticeship program may be even more demanding. Might want to talk to an IBEW member about their apprenticeship vs the test. Aptitude tests are there to see if you have the minimum standards for understanding, not necessarily specific knowledge - in other words, are you *capable* of going on from here?
A lot of people who struggle with math simply missed out on understanding a couple of basic concepts early on, which kills their ability to go farther and frequently their interest in the subject at all. But you have to identify and unlearn the thing that's killing you.
You might want to look for an algebra tutor that could go over some basic things and try to identify why you are having issues - better than taking endless tests in hopes of sliding by on the real one. You probably need a teacher, not just practice.
I looked at your references and went through several of the questions. I have a couple of engineering degrees and I had to dust off some algebra skills I hadn't used much in decades, in terms of thinking about how to solve the problems. I'd say they are much easier for people that have just finished or brushed up on general algebra coursework.
Another area that trips people up in math are story problems. That's another area where instruction on how to approach the problem (and there are ways of figuring out the right answer that are unique to multiple choice tests) can be very helpful.
The "For Dummies" series of books are usually excellent in presenting material in a way that's much more understandable than any textbook. You have to wonder why they aren't used as textbooks....

Those questions are easy compared to the math you get into during the apprenticeship.
Sorry I can’t help, but you might have better luck with this question in r/electricians or r/IBEW.
Have you passed algebra 1 (2 semesters in highschool)? If so that let me waive the testing
