For those who are interested. The two sites I have been using to prepare myself for the interview are listed below. This is NOT an endorsement! Just helping my fellow pilots prepare for the JAA Exams
JAA ATPL Question Bank | AviationTire.com
This site is free with a caveat. You will only have access to about 30% of the question bank and the practice exam will randomly select questions from that 30%. If you want access to the entire question bank, it cost 49.99 EUR.
jaaquestions.org
This site is absolutely free! The only requirement is that you must register. You have access to all the JAA question bank. It also allows you to take randomly generated exam base on the subject chosen.
The two sites vary in regards to user interface.
