I dont know of CBC but I now know 8-4-4 was not working.
My kid started with 8-4-4 and I thought it was great - they did a lot of things - like we did
Lots of rote learning.
Until I moved her to Cambridge education systems.
Her workload reduced drastically - infact rarely do homework
But her brain opened up - because she was being thought to critical think.
Rote learning doesnt work.
IF CBC is like Cambridge - go for it. It's appear similar - model wise - but do away with rote learning
And focus on STEM - Maths, English and Science - the rest are not very neccessary.
