My score on my last 2 practice tests have been the same. I have been journaling wrong answers and blind reviewing. What are some additional things I can do to help with this?

I have been taking prep tests in chunks as well as in one sitting. How many prep tests should I take in one sitting before I take the real exam in June? Also, I have been getting a 145 before blind reviewing and a 155 after blind reviewing. What are some things besides drilling that I can do to increase my score? I am aiming to get a 160.
