About the Instructor:

This course was created by Ganesh Pai, founder of Don’t Memorise.A voice over artist has been used to keep a neutral tone to the audio of all lessons.

With his love of math and fascination for simplifying complex problems Ganesh made his first educational video whilst tutoring online. Here, he experienced first-hand the ways in which edutechcan revitalize education and the space it creates for anytime, anywhere learning. From this grew his long passion and term vision to create free learner centric ‘lessons’ through technology for students from all walks of life in India and ultimately across the globe.

In 2013 he established ‘Don’t Memorise’ with three core objectives. Firstly, and most importantly all resources always remain free of cost to end users. Ganesh is committed to the belief high quality education is a basic right regardless of economic circumstance. Secondly, all videos follow his ‘Don’t Memorise, Know More!’ philosophy. This entails videos having a strong conceptual element to bridge the gap between theory and application. In general, a simple story format is used to relate theory to real life. Finally, content needs to be relevant in order to have the maximum impact. His educational content can be used by anyone anywhere however it is currently being developed to meet learning needs of students in India.

Ganesh has written the content for over 1,300 math related videos, ranging from middle school math to Test Prep lessons that are available on his website Don’t Memorise (dot) com. He has personally trained and developed a highly capable small technical team to work with him.
