I’ve started working through UPSC previous year questions, but I’m not sure how to review them properly. I can often remember the answer after checking it, yet that doesn’t always help when a question tests the same topic in a different way.
How do you use PYQs to spot gaps in your understanding and decide what to revise next? I’d also like to know whether it’s better to sort them by subject, syllabus topic, or exam year.
