Which is the best school system from the age of fifteen has always been discussed by people all over the world, some people believe that is better specialization in a limited range while many others think that is essential know a general range of subject until they leave school. I will try to address both these views and then I will elaborate my own opinion. Overall, the first pattern probably offers many opportunities for high school and could be better if a child has a clear idea about which way would follow in the future. Contrariwise, I believe that this is not the right model before the age of fifteen, is essential that the child learn a plethora of subjects and not only specific subjects. On the other hand, there is the second pattern that is adopted in many countries in Europe, where the child can study a lot of subject in equal quantities and after, precisely at the age of fourteen can choose at the high school which subject are more or less important for its career.
