A four-hour mock is the wrong tool for a Tuesday. A week wise test is one week of one subject, drawn from every published year at once — short enough to take after a lecture, and specific enough that the report is about something you can fix tonight.

A week wise test is a timed test scoped to one week of one subject, assembled from every released year at once rather than from a single paper. It works because the IIT Madras BS Data Science course is itself organised into 12 weeks, and the assessments follow that structure — Quiz 1 sits on the opening weeks, Quiz 2 on the middle ones, and the End Term on all of them. Every question on Prasnya carries the week it came from, so "Week 6 of Mathematics 2" is a route holding every published question on that week, and starting it as a test takes minutes rather than hours. The practical value is that it matches how you actually study: you finish a week's lectures, you test that week, and the report tells you before you move on whether it landed. Coverage is genuinely uneven across the twelve — the released papers cluster on the early and middle weeks — so the table on this page states what is published in each rather than implying twelve equal ones.

The coverage
Measured across every subject and both released paper sets. This is the only place on the site that states it, and it is worth reading before you plan revision: the weeks are not equally examined.
Counts are field-wide for that week; each row opens the subject with the deepest coverage of it. Weeks 9 to 12 are thin because the released papers ask less there, not because the material is missing — every subject's own week list is on its subject page.
The habit
The case for full-length mocks is real but narrow: they train stamina and whole-paper triage, and you need a handful of them before an exam. The case against taking them often is arithmetic. A four-hour attempt plus a serious review is most of a day, so you will do it perhaps five times a term — five data points about a twelve-week syllabus.
A week wise test is fifteen minutes and produces the same report. Take one after each week's lectures and by the end of term you have twelve to twenty data points, each attached to a specific week, gathered while the material was still fresh enough to repair cheaply.
The reports compound, too. Because every attempt is filed against the week it tested, the analysis surface can show movement over time rather than a series of unrelated scores — and when a week comes back weak, the level below it is already a route: 304 topics and 660 subtopics, each its own even shorter test.
The subjects
Each subject opens on its own question list, with its weeks as routes inside it.
Week routes are counted across both released paper sets, which is why several subjects show more than twelve — a subject examined in both Quiz 1 and Quiz 2 has its weeks published under each.
The route
Four steps, repeated. The whole point is that it is cheap enough to repeat.
Lectures watched, assignment submitted, material nominally covered.
One week of one subject, every published year at once, on a clock. Minutes, not hours.
Accuracy, marks lost, time against the time each question deserved, and the attempt-quality split.
If the week is clean, move on. If it is not, the weak topic is named and is its own shorter test.

The questions
Start with the free day, test the week you just finished, and find out tonight rather than in the quiz.
