i have the Jeremy Pratt books, however I also purchased Oxford Aiation training cd roms, Practical Flying & Airlaw, I have to say, its so much easier,
I watch the lesson Im going to take next, on the cd, it just sinks in,
with the airlaw cd, there's even a test for each section, without a doubt
I would recommend them, I do not work of them either, I believe, if you call them, they supply a taster cd,
