I've read all of the gouges I can find but I really cant find much information on the mesaba written test. Can anyone here shed some light?

I understand it is 25 questions. Is it pass/fail? or how does the grading go?

Any information would be very appreciated!

25 questions, basic IFR procedures and regs that's about it.......plus the wonderlic test...........

If you fail this written test you don't belong anywhere near an IFR certified airplane. But if you passed your IFR written you'll have no problem

Dito. Study part 91 and basic ATP questions. You will do fine. If you don't find the test easy you probably have no business flying for hire, especially IFR.

Thanks for the info guys I appreciate it.
