I would like to know the approximate class size for Gr 6 in CDNIS. Also the class size for Year 7 in Renaissance College. Is CDNIS currently running MYP? According to its website, it says it is. But I checked the IB website, CDNIS only runs the DP. So, which is true? One last thing, between Renaissance College and CDNIS,which one should I go for? Is a Year 6 or 7 class with 30 kids considered a big class?
