:? I am a student at university. I have to learn much theoretical knowledge every day in my college. However, in my opinion, the practical experience and skills are more important than the theoretical ones. Furthermore, the theoretical knowledge are always reverse of the practical application. Besides these, the world develop more and more quickly, some of the theoretical knowledge is out of date and useless. Therefore, why we must learn so much theoretical knowledge rather than take part in some training for practical skills?
