Alex,
As usual you are simply interested only in selling your ATPL "database" question bank. Any posts on this site can only re-enforce your sales.
Your "database" is full of out-of-date/erroneous questions and I feel that you are a con-artist in making the gullible pay extortionate prices for garbage. Many of your "questions" and "answers" are simply beyond belief. I can say this with absolute "AUTHORITY". Congratulations on the success of your school.
