Good day! I have read from most people here that Amit Kalani's book is really very good for C# exam takers..Got a question though regarding the difference between Amit Kalani's Training Guide series versus the Exam Cram series, which is cheaper. :) Can anybody that have read these give out the difference? Do the TRaining Guides really have more content than the Exam Crams? About approximately how many percent content is the difference? Thanks, newbie
