Bydd penderfyniad ar gyflwyno fwy o blant i ddysgu wyneb i wyneb yn cael eu hystyried fel rhan o'r adolygiad 21 diwrnod nesaf ar 19 Chwefror pan fydd gennym fwy o fanylion am unrhyw newidiadau.
Any further phasing of more year groups will be considered as part of the next 21 day review on the 19 February when we have more detail around any further headroom.
