Do you guys actually feel that TSD is the toughest?

its not tough,but ya its the lengthiest so far....u need atleast 5 days just to learn the concept and then practice for another 3 days to ace it...give it proper time then only u can ace it

The application of concepts varies question to question, so yes it is a bit tricky but practicing will make it doable.

I watched PW classes

PW classes was too good it was like 1.5 hrs long just 2 videos, concept will be clear don't skip and also pause and do the problems take time to watch, i feel genuinely better after that .
