Consumer reviews skew mixed-to-negative: classes are far larger and less personal than the “small, interactive” marketing (its own site concedes up to 28 per batch), with recurring reports of unqualified or absent teachers and weak academic value. Parents also cite serious admin/billing friction — currency-mismatch charges, portals blocked over late payment, and at least one admission cancelled on the planned payment day.
