Only want to include your GPA if it's perfect, and if not, leave it off. It's only possible to include your GPA if it's perfect because, typically, it's just going to draw attention to the fact that it's not good. Unless you're at the top of your class or something along those lines, you don't want to include it.
You can if you did well in college, sometimes included, but in most cases, for law firm resumes. You're much better off leaving it off unless it's exceptional, and that's when people get more senior. It's the same thing. Even if you were in the top 15% of your class at a good law school, you typically wouldn't leave it on.
Unless there was some reason to because it starts looking a little weird, and you can put the order of the coif on there, and you can put. If you've visited Columbia many times, I think the top third is like a heart and fist on the scholar. So it may be better than that. I'm still determining what it is, but sometimes people will put those things there. But other than that, it's not necessary.
