The IIT Madras BS degree has plenty of study resources, but they solve different problems. This guide sorts them by what you need and what to look for, so you can choose what fits your term.
Short answer: for previous year papers use Quiz Space; for notes and lectures use the free notes and YouTube lectures from Unknown IITians; for grades and scores use the grade calculator. The details are below.
Past papers are the quickest way to learn what an exam expects. Look for papers organised by subject, exam type (Qualifier, Quiz 1, Quiz 2, OPPE, End Term) and year, ideally with an answer key and a timed mode that feels like the real exam.
Week-wise notes that follow the course structure save the most time. Unknown IITians offers free week-wise PDF notes for IITM BS Data Science and Electronic Systems subjects, organised by level and subject.
A good calculator applies your course's official grading formula, covers your branch and level, and shows both your total score and your grade. Unknown IITians offers a grade calculator and score checker, a CGPA calculator and a marks predictor for all four IITM BS branches.
If you want lectures and doubt-solving on a schedule, look at live batches: check what level they cover, how long they run, and whether recordings and practice papers are included. Unknown IITians runs live Qualifier and Foundation courses for IITM BS.
Study groups help most when a subject gets hard. Unknown IITians lists IITM BS communities and study groups on its communities page, and there is a Telegram community for IITM BS students.
