What is the best way to solve IITM BS PYQs?

Solve IITM BS PYQs by week rather than by paper. A released IITM BS paper mixes a whole term into one sitting. Working through it front to back asks you to recall material you studied months apart, and it leaves you with a score you cannot act on. The faster order is simple. Take the week you are being taught right now. Solve everything that week has ever been asked across the released papers. Only then sit a full paper against a clock, to test your timing. Prasnya is built for that order. Every previous year question carries the exam, subject, week, topic and subtopic it came from, so a week is a route you open rather than a search you run. Any slice of it can be started as a timed mock. The report afterwards names the topic that cost you the marks, so your next session repairs something specific instead of covering the papers again.

The assessments

Qualifier, Quiz 1, Quiz 2 and End Term — each with its own route

The papers are the same ones everybody has. What changes is that here they are already sorted into the weeks and topics each assessment actually examines, so a revision session can be aimed rather than general.

What you get

What Prasnya adds to the raw question papers

Six things, and each one exists because a folder of PDFs cannot do it.

01
Every question carries its address
Exam, subject, week, topic, subtopic. That one property is the whole product. It is why a single topic can be practised across every year at once, and why an attempt report can name the topic that lost you marks instead of handing back a total.
02
Any slice can become a timed mock
A full paper, one subject, one week, one topic, one subtopic. Each is startable as a real mock, with a clock, a question palette and a submission you can review afterwards. You are not limited to sitting whole papers.
03
A worked solution to every question
Not an answer key. Each question opens with the reasoning written out, typeset properly, so the questions you got wrong are the ones you learn the most from.
04
Analysis that names the repair
Score, accuracy, marks lost, time per question, subject movement, difficulty and attempt quality — perfect, wasted, overtime, confused. Pro adds a question-by-question review of the exact attempt you sat.
05
Filters built for revision, not browsing
Filter by question type — MCQ, MSQ and numerical answer — by difficulty and by year, so a session can be exactly "hard numerical questions from Statistics 2, Weeks 5 to 8".
06
A vault of what you got wrong
Bookmark a question from anywhere and it waits in the Vault with its full context. The point of a wrong answer is the second attempt, and the second attempt has to be findable.

The route

From the degree to the exact topic, in five taps

The route is the same every time, which is the point — you never have to remember where anything lives.

Pick the exam
Qualifier, Quiz 1, Quiz 2 or End Term — or skip the exam entirely and revise straight from the syllabus.
Pick the subject
Every foundation subject, from Mathematics 1 through Programming in Python.
Narrow to the week
Weeks 1 to 12, exactly as the course runs them, so practice lines up with the lecture you just watched.
Narrow to the topic
Then the subtopic, if the leak is that specific. Each level is a route of its own.
Solve, or sit it as a mock
Practise one question at a time with the worked solution a click away, or start the same set as a timed test and read the report.

The syllabus

Every foundation subject, week by week

Each subject runs Weeks 1 to 12, exactly as the course does. It then breaks down again into topics and subtopics, and every level is a route you can practise or test on its own.

Mathematics 1 Mathematics 2 English 1 English 2 Statistics 1 Statistics 2 Computational Thinking Programming in Python

The sources

Where these questions come from

Everything here is built from the papers IIT Madras has already released. Nothing is invented, and nothing is scraped from another site.

Officially released papers
Every question is taken from a paper the BS in Data Science and Applications programme has published. Nothing is a mock question written to look like one.
Transcribed and typeset by hand
Each paper is entered question by question, and the mathematics is typeset rather than screenshotted. That is why you can select, copy and search any expression on the page.
A written solution for every question
Each question carries the reasoning worked through, not just the correct option. Where a question has been asked more than once, the solution covers the version in front of you.

The questions

Questions students ask

What does IITM BS PYQ mean?: IITM BS PYQ stands for previous year questions from the IIT Madras BS Data Science degree. On Prasnya, all IITM PYQ sets are transcribed question by question with step-by-step solutions, sorted into the exact week and topic they came from.
Where can I find IITM PYQ and PYQ IITM BS papers with solutions?: On this page. Prasnya holds the officially released IITM BS PYQ papers for all four assessments (Qualifier, Quiz 1, Quiz 2, and End Term). Every paper is transcribed with worked solutions and organized week by week.
Which IITM BS assessments do the PYQs cover?: All four assessments in the programme — the Qualifier, Quiz 1, Quiz 2 and the End Term — from the officially released papers spanning 2022 - 2026. Because the End Term is cumulative, it is the set that reaches the later weeks the two quizzes barely touch.
Which subjects are included?: Every foundation subject: Mathematics 1, Mathematics 2, English 1, English 2, Statistics 1, Statistics 2, Computational Thinking, Programming in Python. Every one of the 8 is examined in the cumulative End Term; 7 also appear in Quiz 2, with Programming in Python examined in the Qualifier / Quiz 1 and End Term sets.
Can I practise IITM BS PYQs week by week?: Yes, and it is the fastest way to use them. Every question carries its week number, so Weeks 1 to 12 are separate routes inside each subject — and any week can also be started as its own timed test.
Do the questions come with solutions?: Yes. Every question has a worked solution, typeset with real mathematics rather than pasted in as a screenshot, so it stays readable and selectable on a phone.
Can I take previous year papers as a timed mock test?: Yes. A full paper, a single subject, a single week, a single topic or a single subtopic can each be started as a timed mock. Each one runs with a clock, a question palette and a report at the end.
Is it free to start?: Yes. Week wise practice is open to anyone with an account. Work through a whole week of previous year questions and their solutions first, then decide whether the deeper topic and subtopic routes are worth paying for.
Does it work on a phone?: Yes. The practice surface, the timed mocks and the analysis are all built mobile first, with the mathematics typeset rather than served as images, so it stays legible on a small screen.

Timed practice

The papers are public. The organisation is the advantage.

Solve a week of whichever subject is hurting, and see whether the report tells you something a total out of a total never could.
