Definitely not.
It's true that we learn a lot of knowledge from the lessons in school.But there are so many other things that we learn outside school.There are so many life experiences that we learn outside school.We learn a lot from our friends and family.We certainly learn more after we leave school.And I think the most important thing for us to learn in school is to learn how to learn so that even after we leave school,we still know how to improve ourselves by learning by ourselves and from life.
In a word,school education does provide us with everything we need to learn in life.
