Coaching of chemistry for high school students by an experienced faculty (msc chemistry)

he is very passionate about chemistry... he used to take our labs... he used to explain us properly why a particular reaction is occuring.. along with showing us the steps of a particular practical he made sure to also explain the mechanism of it.. he also used to explain us properly why we get a particular observation pr why colour is changing or why on mixing 2 things the temperature of the vessel is increasing suddenly..

And also that he is extremely disciplined, dedicated and hardworking. In my 2 year course i never saw him taking any leave and he has always been very patient in repeating his instructions and explanations till it was clear to each and every student.
