In my letter of intent for an MSc, should I mention my commute? I have a respectable cGPA of 3.5 and annual GPA of 3.7. I am hoping to graduate with at least a cGPA of 3.5 which would award me with "high honours". I am not trying to find an "excuse" for a low GPA (since mine is rather high), but rather emphasize that I was able to achieve those marks while volunteering / commuting. I am hoping this demonstrates my hard work. Anyways, I volunteer on research 3 hours a week (not a huge time commitment). However, I also commute 5 hours total to and from school (so about 25 hours a week simply commuting). I am wondering if this would be worthwhile to mention in my letter or if I should leave it out? I am definitely mentioning my volunteering since it relates to the program.
I'd advise against bringing up anything that might seem like an excuse, so I'd forego mentioning the commute.  That said, this is an EXCELLENT thing to have mentioned in a letter of recommendation that reinforces your dedication.  Try to get a recommender to bring it up.
