LSAT Retake & Reapplying - Addendum Needed?

Hello! I'm applying this cycle and am unsure whether I need to write an addendum.

I took the LSAT six times over the last three years. My first five attempts were all in the 162-164 range, but on my sixth attempt I scored a 173. Earlier this year, I was granted an LSAT retake exemption after being diagnosed with ADHD. The diagnosis and subsequent treatment changed the way I approached studying and testing, and the improvement is reflected in my score.

I also applied to law school last cycle with a 164. Since then, I've raised my LSAT score and obtained a stronger job, so I'm not sure how admissions committees typically view these circumstances. Would it make sense to write an addendum, and if so, should I address everything in one addendum or separate them into two?

Any guidance would be greatly appreciated. Thank you! 😊
