insulting the people who can't find jobs as having no personality or interview skills is not a wise idea. I know a LOT of these people, and I can say that for many of them, this is just untrue. It's a tight market right now, and while I don't think that's an excuse to sit on your butt, it does mean that a lot of desirable people can't find a paying job. Karma is a bitchh on this kind of stuff, so I suggest you stay humble at this early stage in your legal career and be grateful for someone giving you a break.
And no, I'm not bitter--I have a job, I just feel very badly for my friends who (through no fault of their own) don't.

I'm in the top half of my law school at a T1 (30-40 range) and made 10/hr last year, during my 2L summer.  I worked for a solo back in my hometown and it was the only offer I had to do any legal work.  If I were you, I'd take the job and not even ask for more money.  You don't want to sound like you have a sense of entitlement. 

As an initial matter, the others are right and you should check before you include something that the school didnt give to you.  At most schools at least a couple students will drop out in disgust or leave for other reasons after 1st semester.  If and when that happens, you'll be 34 in a class of 132 or 133 and 26% wont be accurate anymore. 

That being said, I'd put a percentage in if I could, and only for the stupidest reason - somehow I think 1/3 instictively comes to mind you look at 34/133 quickly and dont take a second to do the math in your head. 

Regardless, "Top 26%" screams retarded.  I think "26th Percentile" is maybe a better way of expressing it.
