Truly enjoyed the tutorials, especially the ones I was curious to know more about "theory of relativity" and videos on "work and energy". Admire Mr. Kaustubhan Srivathsan to develop an interactive tutorial with videos and audio that makes it easy as cake to understand complex physics concepts. I wished this method was available during my school days, I can imagine, i'd have greatly improved my grasp on modern physics. Also the website (I presume moodle based) is professionally done, kudos to both Mr. Srivathsan and Aditya !!
