I have vaguely heard of Khan Academy. Let me try that out and get back to you. Thanks! Been thinking of finding a platform for English.

It’s meant for parents to do Maths with their offspring at home. Quite ingenious of the school to get the parents involved, I must say. SGD$6000 (I went to ask the Head of Department of Maths for the pricing) for 1000+ students for a year’s subscription — an expense worth taking on!
