Wow that's an awesome diagnostic! You can definitely aim for 180 for June! Buy the basic package and start working on the sections you need help on!! :)
That sounds great to me! The extra time spent reviewing preptests and solidifying basic logic skills is incredibly valuable. I also find it quite helpful to retake preptests after a few months.
i'm doing the same about 5 games a piece but i'm prettt solid on sequencing games and getting decent now at the basic in/out games so it's a work in progress but i am remebering inferences to check and apply!
