Personal question

sir can you give the best approach to get quick and best output from this course ,sometime i feel low while solving question after watching videos

Dnt feel low, It happens that sometimes in one go, you are not able to understand several concepts, so try to clear your basic concepts and if not understood anything, take help from your mentors, your TA’S so that you have a better insight into the topic, and practice more and more questions, then only you will be able to understand things in a more better way.
