The lessons are like videogames and the students learn the subject material and achieve scores. Based on the scores the students advance to the next lesson or do other lessons that are designed to improve certain weak areas. On the way to school the students breathe polluted air, waste their and their parents' time. Transporting the children to school is costly, inconvenient. When children get sick in school a parent has to leave work to take them home.
Schools spread communicable diseases, viruses, bacteria, parasites like head lice.
New antibiotic resistant bacteria make many childhood diseases hard to treat or lethal. Head lice is increasingly becoming immune to treatments. Public schools cannot afford more than two or three obsolete computers per class. The teachers are not up to date with modern technology, communications. The teachers often do not pay equal attention to all students.
