Amit Kalani's Book??

I was looking on internet to buy Amit Kalani's book for
Web applications exam and I came across two different
books with the almost the same title. Please look at the
following links to see the two books (The link might break
to fit in the window, please copy and paste it in

Which book should I buy and what is the difference??
Thanks in Advance.

It depends on how far ahead are you in your exam
preparations. If you are just beginning, then the first
one is for you. And if you are done with the initial
preparations, the second one (the exam cram) will help you
cram important pointers just before the exam....


hope this helps!
