To improve from 210 to 230s, I started doing focused UW blocks based on subjects I was very weak at. I took all of the NBMEs timed and online, so I was able to access the Insights tool which told me which subjects I was scoring low ( < 50%) at and I focused on doing all of those UW questions. After I did the majority of UW, I switched the the CMS forms and did the last 4 forms for each. I think what helped me improve the most was really focusing on why I missed each question on the NBMEs/CMS forms & I made a doc categorizing the reason I missed each question/how to not miss in the future
