I've found a common error with the notation on a lot of lessons:

If you try to print it on A4 paper, or even view it in a pdf reader that is set to print A4, the bottom of the notation drops off onto the next page.

I suspect the cause is whoever writes the notation has his software set to print on "US Letter", which I believe is slighly longer than A4.

I find this to be an annoyance, but not enough to report it every time I find it (wrost culprit happens to be the same instructor who is best at finding mistakes and also answering lots of questions on techniques/theory/etc.)
