Get a short, sharp нож and cut away the shavings to allow the lead to come through. Just make sure Ты sharpen in the direction away from you. Ты don't want to end up with a нож sticking out of your stomach.
Wait until the morning until Ты get to school, borrow a pencil from a friend and ( if Ты stink at math like myself) Рождество дерево the thing. Or! bare with me on this.... dont do it. I prefer the later.
This ALWAYS happens!! I would either use pen anyway, use a нож to sharpen it, go out and buy one, but what i usually do is use the lead bit that broke, или wait until the Далее день to copy off someone. But copying off someone can be a problem because everyonw thinks the same thing, so they come to school hoping to copy off me! So in the end none of us do it:)
