So this happened a few weeks ago, but it was only when my friend told me today that I shouldn't have done it that I worried a lil bit.
In my first Maths paper I wrote in black ink for the first part of the paper, until I came to some sort of diagram where I started to use pencil. After that, I forgot to switch back to pen.
Would this have any affect on them being able to scan my work? If you're told to use pencil for the diagrams I would've thought you could use it for the rest of the paper without problem anyway.
Thank you!
