Science preparation for BPSC Pre exam
Introduction
Science is an important scoring area in the BPSC examination, but many aspirants prepare it in a confused way. The science portion in BPSC Prelims and BPSC Mains is different in nature and requires a separate strategy.
This guide explains step-by-step science preparation for BPSC Pre exam with sources, booklist, and revision method.
Science syllabus difference in BPSC Prelims and Mains
Here you must understand that syllabus of science in bpsc pre and in bpsc mains exam is quite different and don’t resemble each other. General science is to be studied in bpsc pre-exam. Opposite to this Science and Technology (Applied science) is a part of bpsc mains exam syllabus. Now let’s understand definition of general science and applied science for better clarity.
GENERAL SCIENCE – “General science refers to the core subjects of science and not a specialized or applied study of a specific area of discipline of science”. The sub disciplines for general sciences are Physics, Chemistry and Biology. Let me elaborate this definition with appropriate examples; Motion, heat, light wave, sound, metal, non-metal, fuel, electricity, gravitation etc are part of general science.
APPLIED SCIENCE – “Applied science is a discipline that applies existing scientific knowledge to develop more practical applications, such as technology or inventions”. Let me elaborate this definition with appropriate examples; Solar power, renewable energy, bio technology, drone technology, robotics, space technology etc are part of applied science. The development of these applications are based on the knowledge of general science only.
Weightage of science in BPSC Pre exam
Science has strong weightage in BPSC Prelims. Based on previous papers:
- Around 30 questions are asked from science
- Roughly 10 each from Physics, Chemistry, Biology
Difficulty level is usually easy to moderate. A safe target should be:
- Attempt 26–28 questions
- Score at least 22+ marks from science
This section can become a rank booster with limited effort.
Science preparation strategy for BPSC Prelims
BPSC Prelims science questions are objective and fact-based. So preparation should focus on clarity and memory. Best strategy:
- Study basic concepts first
- Focus on factual points
- Revise repeatedly
- Practice MCQs
Do not go into deep theory like UPSC level. Keep preparation exam-oriented.

Note-making strategy for science
Separate note-making for science is not necessary for BPSC Prelims. Better method:
- Underline important facts in book
- Highlight formulas and definitions
- Mark tricky points
- Revise highlighted lines multiple times
This saves time and improves recall.
Revision plan for science section
Science needs multiple quick revisions. Simple revision cycle:
- First reading → concept clarity
- Second reading → fact marking
- Third reading → fast revision
- Last month → only highlighted facts
Short repeated revision works better than long one-time study.
Conclusion
Science preparation for BPSC exam becomes easy when you separate the approach for Prelims and Mains. Focus on general science for Prelims and applied science topics for Mains.
Use NCERT + Lucent, avoid over-sources, and revise highlighted facts repeatedly. With a focused plan, science can become one of the safest scoring areas in BPSC exam.
