I think If failed maths because of what I drew in my paper?

It’s also one of the oldest threads I’ve ever found. Where did you dig this up from?!

Google! I was trying to find out if you could be deducted marks for leaving a note or drawings for the examiner

You could have just asked here. As someone who used to be a trainee teacher, I can tell you it will make ZERO difference. All they see is the question they’ve been assigned and they give marks based on the mark scheme.

They don’t deduct marks, they just don’t award them.
