There is no need to "disturb" or "interrupt" school curriculum.
Not all students or pupils can acquire the same level of knowledge and skills at the same speed at the same time.
Constant assessment for learning (A4L) should be done implicitly to rate the level of multiple intelligences of every pupil. Upon the completion of every A4L, specific level of specific game (aligned to a subject matter) will be recommended to individual pupils. This is like how Coursera pushing courses to me from time to time. However, Coursera is using analytics instead of performance or multiple intelligences assessment.
In this sense, students or pupils are not assigned to a class according to their age, instead, they will compose or be guided to compose their courses at different levels
