Some significant recommendations for CBSE Class 12 Computer Science project work are as follows:- The goal of the class project is to develop realistic and usable apps which utilise Python file handling or Python-SQL connection. It should be done in groups of two to three students and should begin at least six months before the deadline.
- By engaging with local companies or discovering valuable issues, projects should solve real-world problems. For example, developing software to generate invoices by GST regulations.
- Encourage Python library usage and innovation for a variety of applications, such as games, educational software, accessibility solutions for impaired students, and mobile apps.
- Students should be encouraged to study on their own and to increase their knowledge as needed.
- While working on projects, emphasise the necessity of avoiding plagiarism and respecting copyright.
