It's really easy. I had been out of school for 10 years and took it and passed it first time.
I just started the apprenticeship last year. We started with close to 150 people and are now down to 48 or so.
It wasn't that the course is hard, it was the fact that half of those really didn't want to work and the other half didn't like the work in this field.
It has been great so far and I have learned so much in a short period of time.
If you have any more questions I would be happy to answer them or even give you some sample questions of things I remembered seeing on the test.
But to sum everything up, it was pretty easy. Just basic algebra stuff.
