Time every paper from the years that match your exam's current pattern, usually the latest 3–5 years. Use older years topic-wise, only for chapters your error log flags. The right cut-off year depends on when your exam last changed its pattern or syllabus, so 10 years is not a safe default for every exam.
“How many years should I solve?” is the most common PYQ question, and “10 years” is the most common answer. That answer ignores two things. First, exams change: a paper from before a pattern or syllabus revision trains you for a test you will not sit. Second, exams publish very different volumes: one year of JEE Main gives you 10 or more shift papers, one year of UPSC Prelims gives you two. This guide gives you a range per exam family, the reasoning behind each cut-off, and a way to set your own number from the weeks you have left.
Why there is no single number
Four things decide how far back you should go.
- Pattern changes. When the number of questions, sections, duration or marking changes, older papers stop being good timing practice. They can still be good concept practice.
- Syllabus revisions. When topics are deleted, some older questions become irrelevant. When topics are added, older papers under-represent them, so recent papers matter more.
- Papers per year. Multi-shift exams (JEE Main, SSC, RRB, bank prelims) produce many papers each year. Single-paper exams (UPSC Prelims, JEE Advanced, NEET) produce one or two. Count papers, not years.
- Official availability. Some conducting bodies publish full papers and keys. Others publish little, and much of what circulates is memory-based. Fewer reliable years means each one deserves deeper review (see memory-based vs official papers).
Recommended range by exam family
“Timed” means a full paper, in one sitting, under the latest marking rules. “Topic-wise” means individual questions pulled into chapter drills (topic-wise vs year-wise PYQs).
| Exam family | Sit timed | Use topic-wise | Why the line falls there |
|---|---|---|---|
| JEE Main | Every shift of the latest 2 years | Older years back to about 2019, chapter by chapter | NTA trimmed the syllabus for 2024 and made all Section B numericals compulsory from 2025. Older shifts include deleted topics and optional questions |
| JEE Advanced | Latest 5–6 years, both papers on the same day | IIT-JEE era papers for problem-solving depth | Question types and marking change every year, so recent papers show the current range; old papers still teach how to think |
| NEET UG | Latest 3–5 papers | Older papers for NCERT-line Biology and Chemistry | The syllabus was revised for 2024, and from 2025 the paper dropped optional Section B questions. Time older papers to the current question count |
| CBSE Class 10 / 12 | Latest 3 board papers plus the current sample paper | Older papers for long-answer and derivation practice | Competency-based and case-based questions now carry a much larger share than in older papers. 2020–2022 papers were disrupted by COVID-era changes |
| CUET UG | Every year available (only since 2022) | Domain questions from all years | A young exam with format adjustments in recent cycles. Read the latest bulletin before timing any paper |
| GATE (per paper code) | Latest 5 years of your paper code | 10 or more years for high-weight subjects | MSQs arrived in 2021, and GATE 2027 revised paper syllabi for the first time in five years. Check older questions against the new syllabus PDF |
| UPSC CSE | Latest 5 Prelims GS + CSAT; Mains themes from the latest 5–7 years | 10 or more years of Prelims GS for static themes | Static areas (polity, history, geography) recur across a decade. Current affairs questions age fast |
| CAT | All slots since 2020 | Older papers for RC and DILR set practice | CAT moved to a shorter format in 2020. Older papers are longer and differently sectioned |
| SSC CGL / CHSL, RRB NTPC | A spread of shifts from the latest 2 cycles | Older shifts for arithmetic and grammar subtypes | Many shifts per cycle; stage structures have been revised in recent notices |
| IBPS / SBI / RBI | Latest 2–3 cycles | Older cycles for puzzle and DI types | Patterns shift slightly most years, and official full papers are limited |
| NDA / CDS | Latest 5–6 years (both sessions) | Older Maths and GK papers | Stable pattern; UPSC publishes the papers |
These are working ranges, not rules. For exact counts, durations and marking, check your exam’s syllabus and pattern page, for example JEE Main, NEET, GATE or CBSE Class 12, and then the official bulletin for your cycle.
How to set your own number
Start from your calendar, not from a list of years.
- Count your weeks. Write down how many weeks you have until the exam.
- Decide how many full papers you can review properly. A full paper is a timed sitting plus a review session that takes at least as long as the paper. Most students manage one to three a week alongside study.
- Multiply. Weeks times papers per week gives your timed-paper budget.
- Fill the budget newest first. Take papers from the latest year, then the year before, until the budget is used. Stop at the last pattern change.
- Give the rest of your PYQ time to topic-wise drills. Pull older questions only for chapters that keep appearing in your error log (how to analyse a paper).
- Keep two recent papers back. Sit them in the final fortnight as a last check.
A worked example
A NEET aspirant with 10 weeks left and time for two reviewed papers a week has a budget of 20 sittings.
| Weeks | Papers | Purpose |
|---|---|---|
| 1–4 | Latest 4 NEET papers, one a week, plus 1–2 subject sections a week | Diagnostic, pacing for the current question count, error log started |
| 5–7 | Older NEET papers by subject: Biology from 4–6 years back, Chemistry by chapter | Repair the chapters the log flagged; skip deleted topics |
| 8–9 | Two more full papers from the recent set, then sections from the weakest subject | Check that repairs held under time |
| 10 | Two held-back recent papers | Final simulation; no new chapters |
That plan uses 8 full timed papers and turns the remaining sittings into targeted subject work. It covers well over five years of questions without timing anyone on a pattern that no longer exists.
When to stop going older
Stop adding years when any of these is true:
- Your misses repeat. If a new paper produces the same miss types as the last three, another paper adds little. Fix the misses first.
- The questions cover deleted topics. Once a large share of an older paper is outside the current syllabus, mine only the relevant questions.
- You cannot review in time. If papers pile up unreviewed, you have gone past your budget.
- The format no longer matches. An old paper with a different duration or sectioning is not a fair timing test. Use it topic-wise.
Common mistakes
- Chasing a round number. “I finished 10 years” says nothing about whether you reviewed them.
- Timing yourself on an old pattern. Scoring an older paper with different question counts or marking gives you a misleading score.
- Ignoring syllabus PDFs. Before you start a year, mark which questions fall outside the current syllabus and skip them.
- Saving every recent paper for the end. You need recent papers early to see where you stand. Hold back only two.
- Collecting PDFs instead of sitting them. Download one paper, sit it and review it before you download the next (download official papers).

FAQ
How many years of PYQs should I solve?
There is no single number. Sit every paper from the years that match the current pattern under a timer, usually the latest 3-5 years, then use older years topic-wise for chapters your error log flags. The table on this page gives a range per exam.
Is 5 years of PYQs enough?
For most exams, five years sat timed and reviewed properly is a solid core. It is not enough for UPSC Prelims GS, where 10 or more years help with static themes, and it is more than you can time for JEE Main, where two years already means 20-plus shift papers.
Are papers from before a syllabus change still useful?
Yes, for concepts, if you skip questions on deleted topics. They are less useful for timing, because the paper length, sections or question types may have changed. Check every older question against the latest official syllabus before you practise it.
Can too many PYQ years hurt?
Yes. Solving papers without same-day review, practising deleted topics, or timing yourself on an old pattern gives you false confidence. Ten reviewed papers beat thirty skimmed ones.
Should beginners start with the newest year?
Yes. The newest paper is closest to what you will sit, so it shows you most accurately where you stand. Work backwards year by year, and only open older archives once your error log tells you which chapters need extra questions.
