thanks a lot sir. Earlier I used to see how long the video is, and sometimes skip too feeling I can read this in 5-8 mins. Now, I feel these 15 mins video are worth more than 2.5 hrs lecture at coachings. We can literally connect/see every news item from UPSC point of view. As you had previously told to always keep 4 books on study table (mains questions bank is one of them). They were in silos. I had gone through the questions but how to connect them with recent current affairs you are teaching us. SIr, you are literally helping all way round that any sibling/friend would have done. thanks a lot sir
