This repository is a personal academic archive containing lecture notes, lab exercises, assignments, and course materials from my 4-year B.Tech in Computer Science & Engineering program. It's organized by subject for easy reference and serves as:
- 📝 My personal study archive - all course materials in one place
- 🎓 A resource for fellow students - especially those in similar programs
- 📚 Reference for future revision - concepts, code, and solved problems
- 🔍 A searchable repository - browse by subject and find relevant materials
💡 Note: This is an academic resource repository, not a typical coding project. The content includes handwritten/typed notes, lab files, assignments, and reference materials curated throughout my degree.

This archive represents 4 years of B.Tech CSE coursework, organized and preserved for:
- ✅ Personal reference - for revisiting concepts during interviews or work
- ✅ Educational value - helping current students navigate similar coursework
- ✅ Portfolio evidence - demonstrating the breadth of my academic foundation
- ✅ Open knowledge sharing - because good notes should be shared
📌 Important:
- This is a personal study archive, not official course material
- Notes may contain errors, incomplete sections, or outdated information
- Code solutions are my own implementations and may not match "textbook" answers
- Use this as reference and supplementary material only - always verify with your course textbooks and professors
- Academic integrity matters: Do NOT directly copy assignments or lab submissions - use this only to understand concepts and learn
Found an error in the notes? Have additional materials to share? Feel free to:
- Open an issue to report mistakes
- Submit a pull request with corrections
- Reach out with suggestions
