Any feedback on Chengzhu Mandarin Centre at Rochester Mall?

I send my child to the play nest classes - it's an adult accompanied program that starts from 6 months to 18 months. The classes are twice a week on wednesdays and Fridays from 1.30-3pm or from 3.30-5pm. They also have a weekend option. The fees are $1089 per term. Each term is about 11 weeks. There is also a refundable deposit of $200 and a $50 registration fee (unless you have a UOB card, then the fee is waived off).
