hi tot
that CD is a must for the JAA ATPL Met exam, you can avoid bying notes, feedback, etc. It covers the subject in every single details. I have no relation with its realization (unfortunately, although i wish) therefore this suggestion is miles away from advertising. You may see my previous comment and
I USUALLY SAY WHAT I THINK
Best of luck on your studies.
N.B. the subject can be studied in less than a month with no tuition just a determined and constant use of that CD.
