We need to crave for an education system where everybody is able to express themselves freely without the fear of being misjudged, former president Pranab Mukherjee said here on Monday.

"Education is the most powerful weapon which you can use to change the world. The world around us is moving at a fast pace. We don't have time to delve into our conscience. Though a lot of positive developments have taken place in the education sector we still have a long way to go," he said.
