-#### Brainstorming to structure an "Electromagnetism" theme: level 4
-
----------------------------
-
-#### Tips for structuring this level 4
-
-These are **our courses, restructured and redesigned together**.
-
-##### The blocks
-
-In this level 4, **blocks** are important because they **allow to differentiate**
-**students** according to different specialties. Later we can associate a
-metadata in the file, to select certain blocks and suggest circuits
-specific teaching according to the wishes of each student.
-
-So use the blocks to **target different specialties** within this level 4.
-

-
-The Gitlab will be kept up to date with your proposals, also translated into English and Spanish.
-_ (This is not required, but if you can also make your contribution in French, more in_
-_English or Spanish, this will ease the translation work) ._
