important class

I agree with the statement that the most important class can not be taught in classroom. Firstly, I regard the ability to diving problems by ourselves as one of the most important lessons. However, what we are taught in classroom is just the knowledge written in textbooks. Secondly, some essential skills can only be abtained through practice. Like the ability to get along well with others or to swim, which are important lessons and could only be taught in real life.
