Science and technology for 71st BPSC mains exam
Introduction
In this article, I am going to discuss the preparation strategy of science and technology for 71st BPSC Mains exam scheduled in April 2026. This article will guide aspirants step by step on how to prepare applied science topics effectively for BPSC Mains, keeping the nature of the examination in mind.
Science in BPSC exam
Here, aspirants must clearly understand that the syllabus of science in BPSC Pre and science and technology for 71st BPSC Mains exam is quite different and does not resemble each other.
- General science is asked in the BPSC Prelims.
- Science and Technology (applied science) is asked in the BPSC Mains exam.
Understanding this difference is crucial for focused preparation.
Definition of general science and applied science
General science
General science refers to the core subjects of science and not a specialised or applied study of any discipline. It includes Physics, Chemistry, and Biology. Examples include motion, heat, light, sound, metals and non-metals, electricity, gravitation, fuels, etc.
Applied science
Applied science refers to the practical application of scientific knowledge to develop technologies and innovations. Examples include solar energy, renewable energy, biotechnology, robotics, drone technology, space technology, etc.
These applied areas form the backbone of science and technology for BPSC Mains exam.
