How to Read a PYQ Code — and the 2013 Shift Every PSIR Aspirant Misses

Every question in our PYQ Map carries a code: 2024/I/4b/15 means year 2024 · Paper I · Question 4(b) · 15 marks. Two-digit years are shorthand (16/I/1a/10 = 2016). Learn to read the code and fifteen years of papers become a dataset instead of a pile.

The 2013 shift

Read codes across years and one break jumps out: since 2013 the exam asks more, shorter questions — about twenty sub-questions per paper, mostly 10- and 15-markers, against the older pattern of fewer, longer essays. That single structural change rewrote what preparation must produce:

• Coverage beats depth-gambling. Twenty questions sample the syllabus wide; the aspirant who mastered six pet topics meets a paper that touches sixteen. This is why the weightage distribution matters more than depth in any single chapter.
• The 150-word answer is the unit of the exam. Ten-markers demand a complete argument — position, scholar, example, landing — in 150 words. That is a craft, and it is trainable; the playbook drills it.
• Question-families become visible. With ~40 questions a year for fifteen years, the same demands recur in rephrased forms — which is why you study families, not topics.

Use the code actively

When you finish a topic, pull its codes from the map and ask: which years? what marks? which sub-topic exactly? A topic with codes in 11 of 15 years is a standing appointment. A topic silent since 2014 is context, not priority. Worked example from the map: Plato's Popper question appears in 2015/I/3(a)/20 and returns in 2025/I/2b/15 — a decade apart, same family. The code is small; the reading discipline it enables is the whole strategy.
