LSAT Addendum??

Hello, do I took the lsat last year in January. I got a 144. During that time I was studying for the LSAT I was a college undergraduate going through the process of eviction. Which I was evicted and was homeless for a time before I found a new spot. That process lasted up until like right after my LSAT and into the beginning of my spring semester. I am studying for the February LSAT right now. I am not doing so well on it PT wise ( 151 avg score ). Should I just write an LSAT Addendum for my first one and just cancel his lsat and go with that? My UGPA is a 2.9 just graduated this December looking to start law school this fall.
