When should I order my transcript for law school

I am about to take my second LSAT in June, and just finished my junior year of undergraduate and plan to start applying this October. I was hoping someone would be able to answer my question: When should I request my transcript through LSAC? I was just curious as to how long to wait or if I should do it as soon as possible, but my senior year grades and classes would not be reflected so I am a little confused.
