Comments

  • Fenil Behera

    The step-by-step method works. Tried it on yesterday's sectional and saved ~4 minutes.

  • Anand Dutta

    This plus the lecture video is the perfect combo for revision week.

  • Jayant Mukherjee

    Sir, is this enough depth for GATE or should I also do the standard textbook chapter?

  • Saharsh Ansari

    Would love a Hindi summary section for quick revision.

    • Komal Kamath

      Same here — re-reading the invariant section twice fixed it for me.

    • Dhruv Saha

      Try explaining it aloud to someone; that's what made it stick for me.

  • Ajay Upadhyay

    How does this map to the PYQ from 2023? The phrasing there felt different.

    • Faisal Pant

      Good catch — flagged it so the editors see it.

  • Vatsal Pillai

    This plus the lecture video is the perfect combo for revision week.

    • Tara Negi

      It reads fine on mobile for me after the last refresh.

  • Madhav Ali

    The step-by-step method works. Tried it on yesterday's sectional and saved ~4 minutes.

    • Manish Krishnan

      The editor said a deeper-dive follow-up is on the calendar.

    • Deepika Patel

      +1, asked the mentor in today's session and got the same explanation.

  • Bhavin Ali

    Please add a short quiz at the end like the aptitude posts have.

  • Akhil Mishra

    The diagram up top is doing a lot of heavy lifting. More of these please.

    • Rehman Dakait

      Textbook chapter is optional after this unless you want proofs.

  • Paavan Pawar

    Can we get a follow-up post that goes deeper into the edge cases?
