I need some advise as to what should be my action plan for the last 5 days before the real exam. 

So far...

1. Read PMBOK 4th edition - 1 time

2. Then read Rita  6th edition - 1 time (solving questions for each scored 65-75% )

3. Then, took one 4 hour mock test with a score of  68%

4. Then, re-read Rita 6 chapters# 1 to 8 (2nd revision solving question for each scored 75% - 90%).
