By the grace of God, I managed to keep my 4.0. Though, it may very well be the last semester that I can say that, seeing as I am taking Organic chemistry II and Organic lab this semester. Not to mention philosophy (professional ethics), differential equations, and my engineering classes. That brings my total hours for the semester to 15.
The good news is that I am already a junior with 62 hours. :) Add the 15 from this semester and I'll be done before you know it!
