-new course : parallel 1
-
-#####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.
-
-Ya es possible hacer
-I can here :
-- write a full "parallel 1 course" if required
-- or add add a few word about a "course parallel 1" that is written somewhere in "pages/curriculum/..."
-- or do nothing.
