Just some piece of advice from me to my friends on this forum.
First read Rita.
Listen to Prepcast 2,3 times. As advised don't try to memorize the ITTOs. But understand what they are, how they are used.
Then read PMBOK once thoroughly
Answer as many questions as you can. refer to the pmbok as you answer.
Practice at reading questions as fast as possible. make it an instinct to look for words like EXCEPT, NOT, etc
I passed on my 1st attempt. i hope you do too. good luck.
