A lot of schools that have people self report have year by year GPAs listed...this makes it obvious which way you are trending. I know Tuck, MIT, and Chicago all use the same form and have year by year GPA as data points.
Kellogg Class of 2010...still active and willing to help. However, I do not do profile reviews, don't offer predictions on chances and am far to busy to review essays, so save the energy of writing me a PM seeking help for these. If I don't respond to a PM that is not one of the previously mentioned trash can destined messages, please don't take it personally I get so many messages I have a hard to responding to most. The more interesting, compelling, or humorous you message the more likely I am to respond.
