PROS:

CONS:
1)ITS SOLVED PAPERS BUT NOT 100% SOLVED
2)AND ALSO MANY QUESTIONS SOLVED HAVE WRONG SOLUTIONS
3)NO SOLUTIONS AT ALL FOR TYPICAL QUESTIONS
4)G.K.PUBLISHERS MANAGED TO GET ANSWERS SOMEHOW FOR MOST OF THE QUESTIONS
5) STRUCTURAL QUESTIONS GOT NO SOLUTIONS
6)SOME QUESTIONS WERE SOLVED PARTIALLY(I DONNO WAT THEY MEAN)

Fair Compilation of GATE papers from 2000-2013. But contains a lot of printing mistakes. Also, some questions are completely omitted from explanations as well as answer keys, you'll need to find answers online or from reference books.
Practice papers are of average quality, containing a lot of printing mistakes again.
Go for it if you need a lot of practicing. Not many books have papers compiled since 2000.
