course : level+1

or level+2 if current level=1

or level-1 if current level=4

#####for parallel or other level course :
It will be possible to redirect towards an other page in the m3p2 cursus.
Or to write here some paragraphes separated by html from an other pages, I think.
Or write here a completely new parallel course

For the moment, please wait.
