Dont do the exam. You dont sound ready and you want to do it at your best.This especially applies to a CPL situation where your professional reputation is on the line.
Get some more study done, including reading, test excercises in the exam section of the book, and pay for a few theory lessons from your instructor.
Pay attention to wind correction, true vs magnetic corrections, diversions (in the nav practical exam you will have to do a diversion in the air, unannounced, with wind correction and revised ETA's), and practice estimation of wind coorected Eta's. This is really important in real life if you are flying in marginal condtions and you have to have a concrete idea of the fuel implications of a diversion.
When I did it, it was with some professional help and teaching, and in a controlled way. You need to be able to say something to yourself like ..."I
have now done so many practice exams that i can reliably predict my mark to within a few percent..."
then you know you are ready....
By the way, in the group of CPLs i knew the,guy that got 100 percent was the goy that got a qantas job! A sensible aim point is 90 percent or close to it, as you then know that even with performance anxiety in the exam you probably wont fall below 80 percent. The minimum standards are higher if you go on the the Irex IFR exam so its good to get used to it.
