Query: Great Book for 2001...

I passed my CCIE practical in 2001. Had to re-up this year, so I bought Mr. Bruno's book to prepare. The book referenced the new R&S qualification exam by number (350-001), but the content was for the exam I took two years ago! The written has changed quite a bit. This book is useful for about 50% of the subject matter...
