When was the last time you had heard a cook change the world ? Engineers bring about important changes around you.
The phones you use, the buildings you live in, the air crafts you fly in and almost every aspect of life. A cook's mistake only makes food taste bad, an engineers mistake can cost hundreds of lives. A doctors mistake can kill one person, however, an engineer's mistake can kill thousands at once. The course requires you to be competent that's why many people drop out before he 2nd year. Everyone learns from pre-existing knowledge, other wise everyone would be doing art and craft ( which too requires knowledge from others ). So, before you think that it's easy and point fingers at us, get your thinking right.
