Re: Ready for Air law?
No - the questions in the exam are likley to be very, very, similar.
Unfortunately, the questions that you will need to answer in real life are written differently - and as you've only learned the answers to the questions in that book, and not actually learned the subject, then they are the ones that will let you down - but at least you'll get your 75% in the written exam.
Despite my attack - good luck with the flying (and the exams).
