I need some help

[Sandra B]

I am attending a course to become a teacher of English, at the Teachers Education Programme. I´m in third year.-
In the Oral Expression class, we are dealing with a text written by Gene Kemp, M13 on Form. As far as I know, M13 stands for the designation of a classroom. But I can´t get the meaning of the rest of the tittle (on Form).
I think it´s a kind of game word, due to the text I mentioned above.
Can anybody help me to understand it properly?
Thanks!

If you're on form, you're doing well, getting good results, etc. Also a form is another word for a class of pupils. It can also mean that proper way to behave in certain situations.
