An unorganized gang whose colleagues know nothing ...

An unorganized gang whose colleagues know nothing about each other and contradict each other. This school is very unfriendly and incapable of attracting or motivating their students. If the student is able to do this on his own, then the teachers know how to do it completely within a short time. There is absolutely no line and solidarity between colleagues, which has a very negative effect on the students. There are also many mistakes made by teachers concerning the grades also in the exam class. A bit of a shame that you always have to check your own work and then get extra points. For older students it is unfortunate that the school approach and treatment is rampant and no decent conversation is possible. This is just a small impression.
If you want to save your child and yourself a lot of discussion, bewilderment and frustration, choose a different school for your child.
