How Much Is Too Much?

Dear Anna,
I am a perspective law student and I am greatly concerned with writing an addendum since I feel like I have a lot to explain starting with why i have been arrested. The first time I was arrested was for skipping school and lying about my name so I would assume that is considered fraud (which I was unaware of at the time I was about 12), and my second was for being disorderly intoxicated at age 19. To make matters even worse I really wanted to write an addendum for my Lsat scores since I have my ACT and SAT's scores along with my college grades to actually prove that in no means is my test scores a reflection of my academic capabilities. In a case like this do I write more than one or do I forget about writing one for my Lsat scores. Any advice that you can give me would be great helpful as I am completely unaware of what I should do.
