Trades apprenticeship applications open in Baltimore - any advice?

The training centre near Baltimore opened applications for apprenticeships in electrical and welding trades. Any experience at all would help. Applications close in 22 weeks. How hard is the test?

Thanks for writing this out. I went through something close to it 2 months ago, and it settled down once I kept a simple log of every call and form.

The aptitude test was mostly maths and reading a diagram. Free practice tests online were enough for me.
