This is really off-topic. I have a faint hope at a job promotion. I've already failed the test but so have recent graduates of university level electical engineering. The last time I did this kind of stuff was about, oh thirty years ago, and a little bit about 15 years ago.
The union may insist on a retest, or something. They are monitoring it.

Here's what I need. I did the basic math okay but got lost on putting the whole thing together. I'm looking for a web-site that would have electric math exercises so I could review and prepare. (Luck is preparation meeting opportunity.) There would need to be questions on everything: Ohm's law formula, resistors, capacitators, diodes, AC/DC (resist the urge), gates, the works.

If you can help, thanks.
