Sure. I can help you correct that old GPA, AND....fix your credit report. Just send $19.99 to....

I am obviously being facetious.
Welcome to the Discussion! You came to the right place for help in the LS process. There are quite a few knowledgeable folks here. I am, just like you, a non-traditional student hoping to gain admission to "The Show." I have learned quite a bit here.
My grades for that beer and bong-fogged year are "only" 25 years old, but, alas there is absolutely nothing
to be done to "appeal" them. They will indeed hang out and drag down the old LSAC UGPA. My own recent
degree GPA is 3.97 (over 92 hours), but figure my LSAC average will probably be 3.5 or so.
Many of the more experienced folks here (attorneys Thane Messinger and Morten Lund come to mind) can tell you how best to
include mention of the upward trend of your grades in your personal statement or in an addendum.
From what I have read here, it can have some degree of effect, especially if you can crank out
that 173. In LS admissions jargon, your GPA/presumed LSAT stats are what they call a "splitter."
Good luck!
