I scored 245 on uwsa1 2 or 3 months ago

Hello guys.
I scored 245 on uwsa1 2 or 3 months ago, 238 on nbme17 3.5 weeks ago, and 236 on nbme18 1 week ago with some stupid mistakes. My exam is in 2 weeks and my target is 250. I know the book very thoroughly and I have already solved UW and Rx. What should I do to try to up my score? Or do you think i should postpone the exam?
Would you guys recommend going through other resources or doing more practice(I am aware of nbme19 and uwsa2 but I want something to improve my score not assess me). And if so, what other resources/question banks do you guys recommend?
Many thanks.
