Hey everybody!

Before I graduated from my university, my advisor suggested I write an addendum for my science grades. He has since changed professions and I cannot get a hold of him. His replacement is not very helpful. I completed 3 and a half years of premedical preparation before deciding to go to law school, and quite frankly, I decided in my last semester. There are two rather dramatic events that are described in my personal statement which caused the change. With science grades included, my GPA is a 3.43 and without them, it is boosted to around 3.7. Is there an eloquent way to write an addendum or should I avoid it completely?

Thank you!!!
