Drama CD 2 has a translation:
http://nagumo19.livejournal.com/48310.html#Kazuko: Kaname Madoka-san?
Madoka: Yes.
Hitomi: I wonder what’s wrong, were you feeling sick/bad?
Kazuko: Here you go.
Madoka: Huh? Failed?! (note: literally ‘a red mark’) What should I do!? I’ve turned in to an idiot after becoming a Puella Magi!”
All: Mahou Shoujo Madoka Magica
Madoka: Drama CD
Sayaka: Sunny Day Life!
Kazuko: Okay, every student who failed will be taking a re-test tomorrow. So please study hard!
Sayaka: Madoka~! How’d your test go?
Madoka: Sayaka-chan… I did so bad.
Sayaka: Hm?... Huh, 37 points?!
Madoka: Eee… Don’t say it out so loud like that!
Sayaka: What are you worried about? It’s better than me, I got 28 points. What should I do~? hahaha.
Madoka: Homework and being a magical girl… I wasn’t able to keep up with them both. (alt trans: ‘keep them balanced’)
Kyubey: I’m not trying to comfort/console you but if you think about it, compared to your task/cause, the results/marks of your test is pretty minor.
Madoka: Kyubey.
Sayaka: Oh shut up, when we get down to it, it’s your entire fault right?
Madoka: You’re so terrible/mean, Kyubey. To say that…
Kyubey: Oh for, so you regard the marks of an exam/test as more important than hunting down Witches.
Madoka: Ah, Hitomi-chan…
Sayaka: Hitomi…
Hitomi: Sayaka-san, Madoka-san, I’ll lend you my notes to you.
Sayaka: Huh?
Hitomi: My important/precious friends are in a bind, I can’t just leave them be.
Madoka: Thank you Hitomi-chan!
Hitomi: And besides, I would like to be fight/compete against my rival equally.
Sayaka: Urg. Forget it; we don’t need your notes!
Madoka: Wha-!
Hitomi: Really? I understand then, but if there’s anything I can help you with don’t hesitate to ask.
Madoka: AH! The notes!
Sayaka: ERK! Madoka, on tomorrow’s make up test, we’re going to get a perfect score/hundred points!
