Nothing more to share other than the materials I used (as others already did and that were all I could remember)

(1) Andy's Book and questions - easy.
(2) Questions purchased from "www.pmtraining.com" though it is free on PMI site, I completed all the 22 tests (70-80%) and then use "Create Test" to create 25 questions for each knowledge areas just a day before the exam - very very helpful.
(3) Looked at Rita's book, looks very good, but questions are too hard form, so gave up.

I just want to say thanks for all of you who shared your experience and study materials.

One reminder- Do no forget to divide by 6 when you use PERT (in rush), fortunately, the "wrong result" I got was not one of the options...

Last but not least PMBOK Guide should be read, revisited frequently.

The XLS format of ITTO is very handy if you use the filter feature.
Good luck and have a Merry Christmas and a Happy New year.
