Chinese International School (CIS) secondary education

[wlam]

I am interested in knowing the academic strengths or weaknesses of the secondary education in Chinese International School (CIS).
I appreciate any information or comments.
Particularly, is the Maths subject generally strong in CIS secondary education?
Is the Science subject generally strong in CIS secondary education?
Thank you in advance.
