B.Tech CSE Survival Kit: 55+ GitHub Repositories for Full Semester Coverage
A B.Tech in Computer Science can feel like trying to drink from a firehose. One day you’re debugging a printf statement, the next you’re trying to understand the Byzantine Generals Problem in Blockchain.
Textbooks are heavy, expensive, and often outdated. But GitHub? GitHub is the living, breathing library of modern computer science.
I’ve curated and expanded the list you provided into a Complete Semester/Curriculum Notes roadmap. Whether you are a first-year student struggling with Python or a final-year student grinding LeetCode for FAANG, this guide has a repository for you.
Pro Tip: Don’t try to clone all 55 repos at once. Bookmark this page, and come back to it per subject as your semester progresses.

Final Advice for the B.Tech Student
- Don’t copy-paste lab codes. Use the lab repos to debug your code, not to replace your learning. If you copy, you fail the viva voce.
- Use the Interview repos from Year 2. Don’t wait until 4th year. Start solving LeetCode (Repo #38) in your 2nd year.
- Combine theory with projects. Read the “Compiler Design” notes, then visit “Build Your Own X” (#54) to build a tiny compiler.
- Star this article. You will need to come back to it in your 3rd year when you forget what a “semaphore” is.
