No gel pens
... especially if you're left-handed 
I still reckon they help you write faster though.
Gel pens are horrible, horrible. If you don't want your writing to look like it's whooshed to the left, you have to adjust your grip and arm into a position that slows your writing down to a crawl.
My exam handwriting is a kind of hybrid between cursive and separate letters, as in I join some letters up but not others, so I don't sacrifice too much speed and it's still readable (somewhat) ...
I kinda use a hybrid, as well. Everything is joined except for b, f, g, i, j, p, q, t, x and y. I don't always follow that, but I think that's what happens for the most part. It's kinda quick. I can't say it's legible, though, haha.
Maybe it's because I'm used to writing in a different way, but trying to write in print is quite slow for me. It doesn't look any better, either. It's just the same crummy letters with no lines in between.
Edmund, yep they're called Kilometricos. The ones I used weren't very comfortable, but they get the job done. (Y) For exams, I think I used some uniball ones. They had pretty grips on them.
