hello and thank you for your answer .
i already have a faa frozen atpl and because i dont have the green card it was the come back at home .
i heard that the bristol database questions contains 6500 questions and that the questions are teh same in the exam thats why i asked if it is possible to pass the exam only by using the questions ..some people said yes other said that it is possible for subject like com vfr ifr and air law and human performance ..
but they said me that for the subject like nav and met you have to understand the subject ..
