Saina-
Congratulations on taking the leap and scheduling your exam! I moved my date around three times before I finally told myself "Enough!" and just did it. Sounds like you have done quite a lot of preparation and area ready to take the exam. My suggestion would be to continue to practice areas where you know you are weak or if there are certain types of questions that usually hold you up. If you plan to do any "data dump" with formulas I would sketch that out daily so that it is fresh in your mind leading into the exam. Also, I found it helpful to process map on paper the knowledge areas and process groups. I was able to answer questions more quickly when I could easily place the question into the right context or stage in the project.
Hope that helps! Best of luck to you!
