I took that I.B test of 2006.Its English portion which was quite easy for me as it was just SAT level test.The Pak and Islamic Studies portion too was not difficult.About Maths portion I, should honestly, confess that my judgement has little critical credibility as I did not go prepared because I was busy at University those days;so to say it (Maths portion) difficult or easy someone other should come forward to comment.However, I should add in the tail that it's a quite close competition and one has to prepare hard to see the face of success.
Any way good luck to the hard-working
