Due to teacher illness and further training alone, around one million lessons are canceled or covered by substitutes each week at German schools. OVS provides schools with complete, curriculum-aligned digital lessons. The online lessons can be used whenever a subject teacher is absent at short notice or as planned, or when regular lessons cannot take place l due to school closures. OVS currently covers the entire physics curriculum (grades 5-10), with additional STEM subjects to follow shortly.
