Dear Student,
Unfortunately, diploma students from Bihar or any other state with 10th marks are not eligible for WBJEE exam. This is because the minimum WBJEE 2025 eligibility criteria requires that all students (from West Bengal or other states) must have completed their 10+2 education with Physics, Chemistry, and Mathematics as main subjects to get admission to B.Tech degree.
We hope this information was helpful to you. Good luck!
