+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.
