Thanks for the help
I think its a good idea to get some more resources,.. but the 4th ed. is a good place to start
My personal experience says that Exam Cram and Brain **** are not useful atleast in the CCNA exams. When i took the exam almost 8 months ago the members here suggested me to stay away and no wonder the rule still applies.
