@shweta Ma'am, are these playlists organised in a chapter-wise format? I ask because I've noticed that some of the videos don't seem to align with the topics in the next chapter, which makes it difficult for me to revise effectively. Additionally, I've found the videos challenging to understand at times. Before I begin revising for the speed math playlist or other playlists, I wanted to ask for your guidance: do you think it would be a good time for me to start revision, or should I focus on strengthening my foundation first?
