The WB Board 2026 Class 12 Artificial Intelligence Question Paper with Solution PDF is available here. The WBCHSE Artificial Intelligence exam was scheduled for February 2026, during the Morning Session from 10:00 AM to 12:00 PM.
The paper was technical and logic-oriented, maintaining a moderate to high difficulty level. While questions on AI Ethics and Data Features were accessible, the sections involving Machine Learning algorithms, Neural Network architectures, and Python programming for AI required strong analytical skills. Students aiming for top grades should target a score between 80–95 marks, ensuring accuracy in mathematical logic and a clear understanding of the AI project cycle and natural language processing.
