Schweser Book 6 - Exam 2 or 3?

I have time to do only one more full exam (AM+PM) from Schweser Book 6. I have done the first exam (AM and PM) Those who have taken the SChweser book 6, Exam 2 and 3 - any recommendations on which one to take. Which one was more useful in terms of learning or errors or topic coverage? Choose AM of one and PM of another? I’m done with the CFAI exams and on the borderline. So I want to take atleast one more exam for a confidence boost.
