The effectiveness of online learning does not only vary amongst social class. Studies have proved that online learning can have more of a negative impact on you at younger ages than at older ages. For younger students it is almost required they have a structured environment. Within structured environment, younger students are more capable of growing in discipline and communication skills. It is a challenge for most teachers to make their learning activities fun and engaging to the younger audience. In response to COVID-19, many online learning platforms are making their services free due to the high demand. An online tutoring and educational firm, BYJU's, was one of the online learning platforms offering their services free of charge. BYJU's is based in Bangalore, and has seen a 200% increase in the number of students using their services, due to COVID-19. The coronavirus pandemic has resulted in the largest "online movement" in the history of education with approximately 730,000 students actively attending classes via the Tencent Online school in Wuhan, China. While online learning platforms have began to transition their service to free of charge, some school districts are forming partnerships to offer local educational broadcasts for a variety of age groups. One of the partnerships formulated include The Los Angeles Unified School District and PBS SoCal/ KCET. This partnership is offering educational broadcasts to users varying in age groups. The Los Angeles Unified School District and PBS SoCal/ KCET partnership is offering separate channels designated to specific age groups. In 2000, 76.6 million students had enrolled in schools from kindergarten through graduate schools. Of these, 72 percent aged 12 to 17 were considered academically "on track" for their age, i.e. enrolled in at or above grade level. Of those enrolled elementary and secondary schools, 5.2 million (10.4 percent) were attending private schools. Over 85 percent of the adult population have completed high school and 27 percent have received a bachelor's degree or higher. The average salary for college or university graduates is greater than $51,000, exceeding the national average of those without a high school diploma by more than $23,000, according to a 2005 study by the U.S. Census Bureau. The 2010 unemployment rate for high school graduates was 10.8%; the rate for college graduates was 4.9%. The country has a reading literacy rate of 99% of the population over age 15, while ranking below average in science and mathematics understanding compared to other developed countries. In 2014, a record high of 82% of high school seniors graduated, although one of the reasons for that success might be a decline in academic standards.
