Over the past few years, I have had a website (www.FAATestCodeLookup.com<\/a>) running that helps people look up the knowledge test codes that are generated on FAA knowledge tests. This past week, I finally looked at the report data in searches people have been doing on the site.<\/p>\n

I found that I had a lot more data than I realized, so with some belief in the statistical validity of what it was showing, I compiled some data to share out with the world.<\/p>\n

First, I found that I had 1817 report requests for the Aircaraft Mechanic test and found the following were the top 10 knowledge test codes that show up on mechanic tests.<\/p>\n

\"\"<\/p>\n

The next chart shows exactly what percentage of the test reports those particular codes show up on as a “missed question” subject area, and the specific ACS code description associated with those codes.<\/p>\n

If you are taking an aircraft mechanic test anytime soon, these subject areas might just be worth a little more study time if you want to increase your test scores compared to everyone else!<\/p>\n
