The Commercial and FI test banks are ALMOST the same, but not quite. I'd be
willing to bet a small can of a soft beverage that you could pass the FIA
and AGI if you just studied for the Commercial (and assuming you could get
+90% on the Commercial, offer not valid in some states, see rules for
details).

In the AGI you may get a couple of non airplane questions, Gleims advice is
to guess, worked for me.

Definately when you have the FOI (Fundamentals of Instruction) done do the
FIA and AGI back to back (and you can turn the FOI and AGI results in for a
Ground Instructor cert., easiest certificate you'll ever get, and your CFI
DE won't know you got 76% on the FOI). When you're ready, do the IGI and FII
back to back (same question bank).

Hope that helps, Mat

I am getting ready to take my Commercial written exam. Someday, I
would like to be a CFI. I have heard that the written tests for the
Commercial, Ground and Flight Instructor take the questions from the
EXACT same bank of questions. Is this true?
