You can ask for the test questions in Braille, but it might be to late to 
arrange that.  I am sure the V E will read you the questions, so they know 
you aren't being fed the answers.  I think calculators are okay, but I do 
the math in my head, and their might not be any on the technician test 
anyway.  When I saw it, the tech and general class theory was the same test. 
The code requirement was different.  Well with no code requirement, I can't 
help you with the tests.
I don't think I would have passed my extra, with out having that test under 
my fingers.  Then again, that's why I am a Braille reader.  Many of us 
unfortunately are not.
