Mr. Desam Sudhakar has been teaching Chemistry for the Students of 10+2 level and acted as coach for IIT & and Medical aspirants for the past 15 years and guided them to achieve their goals. Mr. Sudhakar is post graduate in chemistry with distinction and later on completed Post graduated in Environmental Management from University of Hyderabad.

Sudhakar's passion for teaching Chemistry and over 10 years of research on various Teaching Methodologies led him to develop this course. Sudhakar has referred several books to prepare just the right content. He has worked incessantly to find the right images and examples for the animation rendering his own voice for the videos.

The videos cover all sub-topics of Chemistry viz.. Organic Chemistry, Inorganic Chemistry and Physical Chemistry. The best part of his effort is that he has created video content covering every aspect from basics to advanced level. All the videos have illustrations provided in animation form. Sudhakar has used real life examples to make the learning process easy.

The main objective of this effort is to provide top quality videos with day to day life examples so that anyone can learn Chemistry easily. Sudhakar strongly believes that his courses would have a huge impact on learning process of students while it can also aid the teachers in enhancing their teaching methodologies.

Sudhakar's passion has driven him to write articles. His following articles were published.

Environmental Public Hearing a Remedial approach Technical Paper at National Workshop.
Healing Touch to Endangered species – Great Indian Bustard - Published in TIGER PAPER, FAO, UNDP, United Nations.
