This differs according to spatial restriction.
We understand that parents tend to prefer fewer children in one class, however at HEGURU, we lay importance on “morphogenetic (or morphic) field”. “Morphic field” is inherent and collective memory of experience existing in space thus leading to faster and easier success when in a room full of others who have succeeded before.
Therefore children learning together with others who are better, work for the better. This is how we calculate class capacity.
