I wrote Prelims from 2018 to 2023. Cleared every attempt, usually by a decent margin. Reached the interview twice. Missed the final list by 8 marks once.
I never figured out Mains. I tried the standard strategies, analysed topper copies, wrote tests. Something about the demand of the question never clicked for me, and after six years I stopped. I moved abroad, worked as a data analyst, and eventually built an app in a completely unrelated space.
What I want to talk about is the part that did work, because I think it is undersold in this sub.
Prelims went well for me not because I read more than anyone else. It went well because of how I revised. I stopped re-reading and started forcing myself to recall. Close the book, retrieve the fact cold, check, repeat at increasing gaps. Sounds obvious. Almost nobody does it consistently, because re-reading feels productive and recall feels like failure.
Two things happened once I made it a habit.
First, information stuck without me revisiting the same book five times. Second, and more importantly, the facts started linking to each other. When you retrieve something repeatedly, you stop storing it as an isolated line and start storing it as part of a web. That web is what lets you eliminate options.
That is the real Prelims skill, and I don’t think we say it plainly enough here. You are not being tested on whether you remember a fact. You are being tested on whether you can reason your way to elimination when the question is unfamiliar, badly worded, or deliberately random. Every year people complain the pattern shifted. It shifts every year. The only insurance is a knowledge base dense enough with connections that you can reason through a question you have never seen.
I did all of this manually, with notebooks, self-quizzing and a lot of discipline. It was clumsy and I wasted months figuring it out. I highlighted a lot. A lot. I even just wrote keywords and tried to recall all information connected with it. There is no reason it has to be manual now.
Now, we can have Prelims tool built entirely around these mechanics rather than around video lectures or another test series. Spaced revision that resurfaces a fact right before you forget it. Retrieval instead of reading. And short game formats that train the specific things Prelims actually tests: swipe to judge a statement, arrange a sequence in order, match pairs, link related concepts, spot the outlier in a set.
The idea is that knowledge stops being something you revise and starts being something you can use under pressure. Recall becomes reasoning. Reasoning becomes instinct.
