508 on both exams!!!!

I am always willing to do a first try even just for a failure to test out how the question is conducted, and get myself to familiar with the exam content. This is the strategy for the other 4 exams I passed in one and a half years. I purchased Amber's book after my first failure of PPD and the first failure after PDD because I realized that I was hitting a stone that seemed my old strategy was not working anymore.  

So far, I tried 3 times in PPD and 2 times in PDD. I got 508 on both exams. I kind of stuck in here. Appriaxmtly speaking, I probably just need 10 more questions and 5 for each then I will be done. But my performance in each section keeps up and down, some improve some go down. But generally speaking, they are very even compared to the passing percentage.

Every time when I finished the exam and recalled as much as I could to determine what I was missing, there was no surprise from the exam at all. I don't know what else I can do to pass the exam at this point since I was so close, I lost the sense of what I should pay more attention to. 

BTW one thing I noticed is that sometimes there is a verb in the question that I don't know the meaning of since English is my second language so I won't surprise miss that couple of questions (maybe one or two). I don't see how that "word-to-word translation dictionary" will help me because I couldn't foresee what word I don't know in the exam anyway and adding more exam times doesn't matter that much either cause there is always an hour or 50 minutes left in every exam for me to go back check my flagged questions. 

Any suggestions and strategies could help and I appreciate it.

Thank you for your patience in reading my long long comments. Wish everyone a happy day.
