In Cameroon, there are two sub-educational systems, one based on French education taught in French and the other one based on British educational systems taught in English. So, in Cameroon this grade will correspond to "Class Two", for the English sub-educational system.

In the French speaking school, this will correspond to the "Cours preparatoire (CP)".
