Some helpful posts here, having just bought the OAT CBT pack from Transair as well. Started Air Law and have so far found the style suits me. I agree that some of the images/media do appear a little crude, but they have all got the message across so far. I loved the parachutists one..
Personally, prior to the exams I'd feel more comfortable having books to read through to ensure I haven't missed any detail - so shall be looking to get an up to date set very soon. I also want to ensure I truly understand everything.
AlphaMale, good luck with your studying and flying

Have seen your posts around here for a while - now I am finally starting training have decided to begin posting.
Once I've done a few of the exams I'll post an update on what I thought of the different study materials..
