What does melinda write her extra credit report about in the novel speak?

In the novel "Speak" by Laurie Halse Anderson, Melinda doesn't write an extra credit report. She's a high school freshman who is struggling with trauma from a sexual assault that happened over the summer. She has stopped speaking and is withdrawn from her peers and teachers.

Melinda's silence and struggle are central to the novel. She doesn't participate in class and doesn't complete assignments. The focus of the book is on her internal journey as she tries to cope with her trauma and find her voice again.

The idea of an extra credit report is not part of the story.
