Quick question on the statement of purpose...

[sacredsweet]

Perhaps as a means of procrastination, I thought I'd ask a pretty stupid question: when discussing theses (undergraduate and Master's) in the statement of purpose, is it at all appropriate to mention the grade received, if it was an "A," or else the foreign equivalent of an "A"? I'm torn. All of my attempts to sneak it in the text have seemed tacky at best. I've seen example essays that mentioned various awards received, but in this case my only honor was a very good grade. Should I mention it? And if so, how?

Thanks in advance.
