💻 Computer Science Project (30M Practical)
Framework
- Requirement: A Python-SQL integrated application.
- Topics: Hospital Management System, Library Management, Railway Reservation.
- Mandatory: Use of Binary Files (Pickle) or CSV files, and at least 3-4 SQL tables with Joins.
✍️ The "Senior Sibling" Viva Hack
- Know Your Sources: Don't just copy. The External Examiner will ask "Where did you get this data?".
- Handwritten vs Printed: Most schools allow printed for 12th, but check with your teacher. A well-organized spiral binding is standard.
- The "Safety" Question: In Chemistry/Biology, be ready to explain the safety precautions you took.
Command Integration: Use /ia-plan to get a week-by-week timeline for completing your projects before the January Practical exams.
