How many children in a class Mexican school?

There's no single answer to how many children are in a Mexican school class. Class sizes vary greatly depending on factors like:

* The school's location: Rural schools often have smaller class sizes than urban schools.

* The grade level: Lower grades may have smaller classes than higher grades.

* The school's resources: Schools with more funding may be able to afford smaller class sizes.

* The type of school: Private schools might have different class sizes than public schools.

While there might be official averages published by the Mexican government, these are just averages and individual classrooms will vary significantly. You'd need to specify the school and grade level to get a more precise answer.
