Good luck.
The reading is straight forward. Read the whole section first, then look at the questions. The questions from the selected reading are usually about details. Just try to remember where information is in the reading that way you can refer back when you answer the questions. I can tell from your post that you shouldn't have too much trouble from the reading portion.
The math is a little more difficult. Besure to know fundamentals like substitution and transposition. Refresh on graphic equations, especially the linear ones. There are only a couple parabolic ones. The questions that threw me for a loop were the ones that asked: 1, 17, 22, 34, which number comes next? That wasn't a real example so don't try and figure it out, but I tried to make it too complicated and the other guys who figured it said it was simple addition.
The real distinction is made in the interview. Dress nice, not like a douchebag, that is button-up shirt, slacks, belt, and decent shoes, shaved, haircut, you get the idea. Since you are already a union carpenter, you are probably made. But, take pictures of your best work and bring them in a folder along with a few other official looking items so they have something to look through at the interview. There are three questions they ask everyone, its been along time so I'll paraphrase: What are 3 qualities that make a good electrician? I say Quantity, Quality, and Attitude. Why should we accept you? I say because I will keep applying until you do. And there's one more but I forget it. The number one quality they are looking for is confidence.
Introduce yourself, common courtesy, etc.
The tests are just to screen-out, the real list is made off the interview.
One of the best electricians I ever worked for never even went to high school but could do trigonometry in his head. I've had nothing but the highest respect for hillbillies ever since. I am glad you are applying, us electricians have got to stick together.
