Is CFAI book's back questions enough to pass? single, into, completed, practice, purchase

If I do every single question at the back of the books of CFAI, is that enough to pass? Or should I purchase one of Kaplan or Elan guides for more practice?
Also, am i too behind right now?
I have completed Ethics (just read, no memorizing), FIxed income and part of Quantitative methods - upto mean / median mode. Thats all.
What take should I take on my studying now? I mean, there are only 3 full months left. (Mar, apr and may).
Also, I can put about 6 - 7 hours into studying starting tomorrow.

You plan on studying 6-7 hours a day for 3 months?

Actually, I would say that if you can really do all the examples within the pages and the EOC questions, you should be very comfortable in passing

You should be fine.  I quiestion though whether studying 6-7 hours a day for 3 months is realistic.  You will get burned out and that might hurt the exam results.
