I felt the same way after taking my National. It kicked me out at 68 questions. I was freaking out! Then I got the result that said I passed and could breath again. But yes you are right the questions were different from the study material but at the same time did not ask anything that you as a basic should know to perform your job properly and safely. So I answered the questions according to what I would do in the field. I start my paramedic course in July. Now I hear that test is a killer!
