ICND knowledge good enough to pass full thing?

I have the ICND half of the ciscopress certification book.

anyway, i also could the intro book but i feel that it is too general. I dont want to waste my time but im not too sure. ICND does have a little review of everything before they go into the better details of the subject.

I do have the full version of the Boston Netsim as well.

So If I know everything in the ICND book along with doing the simulator, I should be fine for the full CCNA. I really dont think there is something in the INTRO book that the ICND book does not have but I feel I need to be possitive before taking the exam so I wouldnt waste money.

Thanks,
