Hi

I have my exam scheduled in 3 weeks from now and have read PMBOK and Rita once ..thinking of devoting last week for exams and reading my handmade notes and glossary of PMBOK..few of the mock tests i have taken i am scoring 65%  

Now i want to know should i read heads first now or rita again ...rita i found didnt illustrate ITTO nicely like the way its given in PMBOK and the tone often tends to demotivate and scare
