How many years of PYQs should you solve for UPSC Prelims?

Ten recent years is a strong default, not an official rule. Your real target depends on preparation stage, available time and whether you are analysing questions or only accumulating completed papers.

A practical default

Complete a 10-year core. Use the latest five years for the closest pattern signal, the preceding five for breadth, and add older papers only after analysing the core. If time is short, do five years well.

Choose the target that matches your time

Available time	Recommended core	Priority
Under four weeks	5 recent years	Analyse recent papers, preserve one diagnostic and revisit errors
One to three months	10 recent years	Subject sets plus several timed full papers
More than three months	10-year core + older selected papers	Two-pass practice, error reattempts and exam simulation

This is UPSC Genie editorial guidance, not a number prescribed by UPSC. The right amount is the largest set you can attempt, review and revisit without displacing core revision.

Why “years completed” is a weak metric

Two aspirants may both finish ten years. One checks answer letters and moves on; the other records confidence, audits options, corrects one concept and reattempts errors. Their completed-paper count is identical, but the second has trained knowledge retrieval and attempt judgment.

A three-pass schedule

First pass: subject learning

Use small sets after finishing a subject block. Note only reusable gaps and traps.

Second pass: mixed retrieval

Mix subjects and reattempt previous errors without reading saved explanations.

Third pass: exam mode

Attempt untouched recent papers under two-hour conditions with official negative marking.

When to add older papers

Your 10-year core is complete and analysed.
You need more examples in a weak static subject.
You can distinguish durable concepts from time-bound factual context.
Adding older questions will not consume your protected revision and mock-test time.

Older papers are valuable, but the exam environment and factual context change. Use them as additional question-pattern practice, not as a promise that topic frequency will repeat unchanged.

Build your own 5-, 10- or 15-year cycle

The live bank spans 2011–2026. Select a year or subject, attempt a small set and let your errors decide what to revisit next.

Frequently asked questions

Are 10 years of PYQs enough for UPSC Prelims?

Ten recent years provide a strong pattern and practice base when analysed properly. They are not sufficient by themselves; static learning, current affairs, revision and timed tests still matter.

Can I solve only 5 years if time is short?

Yes. Five recent years analysed carefully is better than 15 years rushed. Preserve at least one paper for a timed diagnostic.

Should beginners solve 15 years immediately?

Usually no. Beginners benefit more from small subject-wise sets, then a 10-year core. Older papers can be added after the first cycle.

How many times should I repeat PYQs?

Repeat errors and uncertain questions after a gap. A full second pass is useful, but it should test reasoning rather than memory of answer letters.
