Bit of a specific request. My GPA/LSAT are 3.46/169. I graduated in 2011 and have pretty solid work experience and strong extracurriculars. So far I've gotten waivers from Penn and Michigan. Looking at LSN it looks like people with my numbers have been admitted to both at decent rates.

Here's the issue - the latter half of my college years were sort of marred by mental health issues related to a side-effects, dependency, and withdrawal symptoms for a medication I was prescribed but in hindsight should have never been taking. I went from straight A's my first two years to a basket of B's and C's my later two years.

I plan to write an addendum for this for top 5 schools - because I figure my chances there are slim anyway, my gpa (and probably LSAT) will absolutely be an issue for them and explaining the circumstances can only help

For schools like Penn and Michigan where I have a waiver, should I bother explaining anything? Or will the explanation just hurt my already okay chances? The worst on my transcript are a few C's Junior/Senior year, and then a withdrawal (non-punitive) from 3 courses my last semester.

What about other T-14 schools where I don't have a waiver. Addendum or no?

Thoughts are appreciated. Thanks!
