I started out with a subject for my project. But there was barely any information on it. So I found another one and asked my teacher to change it. She got very annoyed, but said yes. But my research isn't going very well with this subject either. Now I found yet another subject. Now I want to ask my teacher to change it again, maybe using email, maybe during class. But how, when I have already asked her once? I don't want her to get mad or even say no. I don't want to turn in a project with very little information either! But I'm afraid the teacher might decline, get mad, say no, or even lower my grade. I don't know, I'm just thinking up what she might do. Should I ask her again? How should I ask her?
