Hey guys, I had a 3.8 GPA before last semester. Then my brother became sick with a recurrent disease at the beginning of the semester. I basically had to commute back home from college everyday because my mom had to take care of my brother and so I had to help out at my dad's business. School took a backseat and so I ended up with C's and B's, couple of them in upper division bio courses. My question is, won't this look weird in the application? I had 3.8s in 1st and 2nd years and then I end up with 3.4-3.5 in my 3rd year. Should I and can I explain this situation in the personal statement? Will adcoms just view this as a sort of excuse for my poor grades in the 3rd year? Thanks all.
