@kunalrv While reasoning is appropriate, the recent trend of using multi-layered, time-consuming puzzles in a qualifying paper is seen by many as a "rejection tool" rather than a "selection tool."

What is your opinion on CSAT? Before 2015, the CSAT paper was crucial, and many candidates who scored merely 60–70 marks in General Studies were able to clear the Preliminary Examination largely because of their CSAT scores. However, since 2015, CSAT has been made qualifying in nature. In my view, the current pattern of CSAT is appropriate and should continue, as it helps assess reasoning ability, English comprehension, and basic mathematical aptitude. That said, the difficulty level and quality of questions can certainly be reconsidered and calibrated.

"History" has the highest "forgetting rate." Spend the last 15 minutes of your day just looking at a Timeline Chart. Don't read details; just look at the dates and the major events. This builds a mental framework that makes the details easier to "hang" onto during the exam.

@kunalrv No Students often confuse the PAC with a constitutional body because it works very closely with the CAG (Article 148). The CAG prepares the reports, but the PAC is the one that actually "grills" the executive on how the money was spent.

Whether Public Account Committee is a constitutional body ?

@gharkekalesh For a young fan, an athlete like Virat Kohli isn't just a player; they are a superhero. The kid probably waited for hours, clutching that bat like a prized possession. To be "invisible" in that moment feels like a massive personal rejection.
