How's the High School in USA?
Absolute hell. They shove a horde of teenagers with minimal supervision into an enclosed building. The teachers have to constantly test and follow arbitrary, uniform guidelines on how to teach or lose their jobs. They are continually making teachers do more, and pay them less, increasing their stress, leading to meltdowns and burnout. Meanwhile, the teenagers are suffering from mental illnesses and bullying, pushing them to psychotic breaks, and easy gun ownership leading to shootings. In short, avoid at all costs.
If you take advantage of it is awesome.
If I had to go through high school again I would do it over the computer.
