Again, I am reporting my progress toward cfi-a. I have passed the writtens toward cfi. Made an 88% on flight instructor airplane and 92% on advanced ground instructor. My local instructor clued me in on the agi trick and so I took that one too since it comes from the same question bank. And again I used dauntless for the study material. There were a total of 1065 questions in the question bank. And I used the same procedure below to study. By the time I went through all the questions I understood the material well enough to even answer questions that I had not seen before of which there were a few on the test. The flight instructor initial seemed to focus more on problems, navigation (adf/vor), and regulations. The agi seemed to cover more on things like engine operation, icing, and weather. That could have been just the luck of the draw at that time. I made sure to review what I missed on the first test and sure enough got a couple of the ones I missed on the second and remembered not to the choose the wrong answer again. Ground training starts today with my local instructor.
Since I used this forum to gather information about how others have done on the FOI written, I will post my results as well.
For the FOI, I used the dauntless app on my iphone/ipad with these options selected, study all questions once, shuffle answer choices, show explanation after each wrong question (and find out why I missed it), enabled question stacks with stack #5 turned off.
Then I answered questions until there were no more left to answer. My thinking is that as questions make it to stack #5 I know it well enough not to waste time on it again.
I made 88% on the actual test. Not perfect but achieved the desired outcome. The questions were mostly exactly like from the dauntless app. There were three questions I didn't recognize and the others I missed were my fault.
So it's safe to assume from my experience the dauntless app will adequately prepare you for the FOI written well enough to pass it. I guess their app has the updated questions since the supposed change back in 2011.
