Lesics

Lesics Lesics was founded by Sabin Mathew, an IIT Delhi post graduate in 2012. At Lesics, we aim to provide quality engineering education.

Our videos are designed to clear misconceptions, create a passion and explain complicated technologies in a simple way. Our videos are designed to clear misconceptions, create a passion for engineering and explain complicated technologies in a simple way.
