Videos are on YouTube and PDFs on Google Drive. Use the GA Solutions page to browse other subjects.
Stats 1 covers describing data and the probability needed to reason about it. It is conceptually gentle but notation-heavy, and the distributions introduced near the end reappear in almost every later course.
Where marks go: Most errors are setup errors, not arithmetic: deciding which distribution a situation calls for is the part worth drilling.
Eleven assignment walkthroughs covering weeks 1 to 11. Seven have a video walkthrough and all have written working.
Files are hosted on Google Drive and open in a new tab. Nothing here requires an account.

Yes. Everything on EduVerse is free to open and free to download. There is no paywall, no sign-up requirement for the study material, and nothing is held back behind an account.
No. The files are hosted on Google Drive and open in a new tab without signing in to EduVerse. Signing in is only needed for features that save things to your own account.

They are worked by students and contributors, not by the course team, so treat them as a second opinion rather than an answer key. If one disagrees with your own working, check the course material before assuming the solution is right — and tell us, because we would rather fix it.
No. EduVerse is an independent, student-run site and is not affiliated with, endorsed by, or officially connected to IIT Madras. Where anything here disagrees with the official course material or the institute's own announcements, the institute is right.
