Measured against the published catalog, 2022 - 2026. Prasnya is independent and not affiliated with IIT Madras.
Practise the subject whose weakest topic is costing you the most marks, and Prasnya is organised so that this is a decision you can make from evidence rather than memory. It holds 3,000+ IIT Madras BS Data Science previous year questions from 24 officially released papers spanning 2022 - 2026, split across all 8 foundation subjects: Mathematics 1 (42 topics), Mathematics 2 (44), English 1 (35), English 2 (48), Statistics 1 (43), Statistics 2 (38), Computational Thinking (30) and Programming in Python (24). Every subject breaks down into weeks, topics and subtopics — 304 topics and 660 subtopics in all — and each of those is its own practice route and its own timed mock. Seven of the eight are examined in both the Qualifier / Quiz 1 and Quiz 2 papers; Programming in Python appears in the Qualifier / Quiz 1 set only. Prasnya is independent and not affiliated with IIT Madras.
The index

Below a subject
Opening a subject is the start of the walk, not the end of it. Each level below can be practised on its own, and each can be taken as a timed mock rather than met four questions at a time inside a paper.
