About BTechi

BTechi started as the BTechi IITian YouTube channel: AI, automation, tech and education explained simply. This platform is the next step, starting with the IIT Madras BS in Data Science and Applications and the BS in Management and Data Science.

Instead of hunting through WhatsApp groups, Telegram channels and random Drive links, students get one structured place: Level → Course → Week → Topic, with notes, videos, books, practice and previous-year questions mapped to every topic.

What you'll find here

• Courses organised week by week, from Foundation to Degree level.
• Previous-year questions for quizzes and end terms, which you can attempt in an exam-style portal and check against the answer keys.
• Practice sets with an explanation for every answer.
• Notes, videos and books, linked from the topic they belong to.
• Qualifier prep: mock exams and quick-revision notes.
• Progress tracking: bookmarks, completed topics and attempt history, saved to your account.

Free to use

BTechi is free. You can browse and practise without an account; signing up just keeps your progress safe across devices.
