I don't understant. How can you have "free time" in computer class ? When you are in class there is no free time. I think you need to talk to somebody at the school to get to the bottom of this. Talk to the teacher itself. You know, kids don't always tell you how it really happened. I am surprised that a catholic school would even have a Dracula book to read. If you can read the book but not draw a picture they are in contradiction with themselve. But maybe the drawing itself of the picture was not the reason he got admonished. Maybe it's when he did it. As I said you need to talk to the teacher and get her/his side of the story.
