Short Addendum Critique Forum

In December 2010 I took the LSAT in --------. At the time of this test I was attending school full-time during the day and working graveyard shifts at night. As a result, my sleeping schedule was somewhat sporadic and I underestimated the effect that this would have on my performance.
I signed up for the test again in June 2011, and after a course of self-study and returning to a normal sleeping schedule, I was able to score eleven points higher on the June exam. I believe that this score is more representative of my abilities.

I'm just wondering if I could phrase any aspect of it better?

Your LSAT addendum is clear & to the point, in my opinion.
