Surprisingly there is no answer key to this old and difficult test. So I created my own after having to take it twice. The answers aren't "official" because I don't have the official answer key, but I tried my hardest to answer them correctly. Most people take this test when applying at manufacturing or engineering companies. Included is also an electrical test that was given to me, I don't know how standard it is, but I added it any way.
I hope that this answer key will help you in getting a job. Know the answers and the logic behind them though, this doesn't give you an excuse to be stupid.
Please add any corrections you find in the comments below. A scan of the original answer key would be awesome as well. Thanks and God bless.
