Science is one of the most important and scoring sections in the RRB Technician exam. The questions are mainly based on everyday science concepts that you have already studied in school, especially from Physics, Chemistry, and Biology (up to Class 10 level). The purpose of this section is not to test difficult theories, but to check how well you understand basic scientific principles and their practical applications in daily life and railway-related work. RRB Technician Science Questions usually focus on fundamental concepts, such as motion, electricity, heat, acids and bases, metals and non-metals, human body systems, diseases, nutrition, and more.
