just from experience and have passed the exam in april 2008 .i studied from the notes borrowed from a student in delhi.you got to concentrate on the basic CPL. like the CP/PNR,flight planing,Navaids,If you study met well there is about easy 40 % is met questions.then the navigation. if you can do the flight planing and CP/PNR questions you can easily get 80 % or so
Its not a hard exam but you have to know the basics and got to be very careful in reading the questions.
hope this helps
