Tips:
-- Use your time wisely. When in doubt, mark the question and revisit it later.
-- Read the question carefully. Read it twice if need be.
-- Understand ITTO's. No need to memorize.
-- Memorize Page 43 of PMPBOK - All 45 processes are listed.
-- The PMP exam questions are much harder then most of the prep exams outside (except for PMStudy and PM exam simulator)
-- When tackling questions, always think from a big project perspective.
-- On the Exam: Use the first 15 minutes to braindump all the EV formulas and process chart.


Best of luck.
