Hello Colenius
Passed PMP in first attempt.
Subscribed & studied Prepcast course, Formula guide and some sample questions from internet..
I prepared short notes after reading each chapter from prepcast CD ( 1-2 pages for each chapter) . Studied formula guide 2-3 times..that was enough to pass exam.
my advice.. do not study too many books or courses.. just concentrate what you have in hand and prepare your own short notes + study each and evry formula concept properly...Stop reading completely 2-3 days before exam.
