I know you are only supposed to comment on grades in your PS when they are really sub-par (like a C or something) but up until this past Fall semester I had straight A's with 1 B+ in 2.5 years of school. This past fall I got a B-/B in orgo 2 (lecture/lab) and a B+ in physics 1. I dont want the adcom to think I was overwhelmed by the coursework. It was due to tons of personal stuff going on at the time (I got engaged the weekend of hurricane Sandy, and my fiance is from Long Island and suffered a lot of damage in the storm, so I didn't exactly focus as much as I would have liked to). Should I include this in my PS or not?
