How does education in countries around the world differ#1

1. literacy rates in different countries
2. graduation rates in different countries
3. schools resources in different countries
4. how countries encorporate religion/customs through school

I already know that the schooling in Africa is not as high as in other places in the world such as Europe.  Also, there is not a large percentage of graduation in Africa. Also, some countries encorporate religions and customs in school.
