Well Guys
Sorry to here about your failure.
I failed my first instruments exam in June because of the Tacho questions.There were about 12. I have now passed the instruments exam , august sitting. I found very little feed back on the tacho instruments so I read and re-read the darn subject and it's paied off.
Now I could do with some feed back on the latest Principles of Flight questions as they are nothing like anything I have seen before .
Good Luck
