Does achieving a degree means that you have become a civilized and educated human being? I don't think so. Getting knowledge won't make you an educated person. The most common example of illiteracy by educated people is when there is littering iin educational institutes and illiterate people are hired to clean the mess. cramming your course books won't bring wisdom, it will only bring knowledge without enlightenment.
You are right my friend. Graduating is not enough for being well educated person. But also you have to improve yourself with experiences of life school. When you may use knowledges that you learned in college in real life, then you will be different from many people and this character will open many ways for success.
