Concerning the R/T theory I agree strongly with Evo 7 - stick with CAP 413 as Thom isn't really appropriate.
After doing Air Law July 2001 and not doing any other study since Jan this year, I've just managed to do the remaining 6 exams within the 12 month period.
Read Thom, do the Confuser, then focus on the questions you get wrong. Re-do confuser night before and you should be ok.
There are no R/T questions in Confuser but there are very useful questions in Pratt.
