Hello Folks -

 I purchased - PMP Exam Prep, Sixth Edition: Rita's Course in a Book for Passing the PMP Exam, last year thinking that I will complete my PMP exam before Aug 2011 however that did not happen and a new edition came up - 7th edition.
 

I still have 6th with me and I am preparing out of the same...planning to take exam by June/ July

Do you think I definately do need to buy the 7th and 6th wont work out. I am new to all this forum, appreciate your help!

Thanks

Miner
