For MPSC Aspirants targeting the MPSC Combined examination, the Science section (General Science) is often the most unpredictable. While Biology carries the bulk of the weight, the 6 marks dedicated to Physics and Chemistry (P&C) are often the deciding factor that separates selection from the shortlist. These subjects act as the 'swing vote' in your Prelims score.
To ensure your MPSC Preparation is targeted and highly effective, we turn to the expert guidance of STI Dhanashree Gaikwad. Her Science Strategy focuses purely on high-yield, recurrent topics in P&C—a surgical approach that guarantees maximum marks for minimum effort in the final stages. This guide provides a clear Study Plan to secure these crucial 6 marks, moving you closer to securing MPSC success.
As per the MPSC Syllabus and recent Previous Year Question (PYQ) trends, the 15-question Science section is typically split as follows:
Biology: 8–9 Questions
Physics: 3 Questions
Chemistry: 3 Questions
Many MPSC Aspirants tend to neglect P&C, dedicating disproportionate time to Biology or other General Studies subjects. However, these 6 technical questions often have direct, objective answers. By dedicating specific, focused revision time now, you can reliably secure 4–5 of these marks, giving you a critical competitive edge over rivals who simply skipped these subjects.
The MPSC often goes deeper than just defining a concept; it tests the evolution of a scientific theory. For Chemistry, the focus must be on the historical development of the Atomic Model.
Instead of just memorizing the final atomic structure, your MPSC Revision Strategy must cover the chronological development:
Ancient Philosophers (Foundation): Revise the fundamental concepts proposed by ancient thinkers like Rushi Kanad, Leucippus, and Democritus. The MPSC frequently asks about these foundational contributions.
Classical Models: Give maximum attention to the theories presented by Dalton and J.J. Thomson.
The Gold Standard (Rutherford): Thoroughly understand Rutherford’s Gold Foil Experiment and its key conclusions, which established the concept of the nucleus.
A critical MPSC PYQ trend highlighted by STI Gaikwad is the focus on limitations and objections. You must know:
Why Dalton’s model was insufficient.
What were the shortcomings of Thomson’s 'Plum Pudding' model.
Why the next theory needed to be proposed.
This is where your knowledge from 8th, 9th, and 10th standard textbooks (the authentic sources for MPSC Science) becomes essential, providing the conceptual clarity needed to answer tricky, statement-based questions.
The MPSC Combined exam tests your practical understanding of Physics concepts through their real-world applications. Do not waste time memorizing complex derivations; focus on the utility.
Physical Quantities and SI Units: You must be able to instantly recall and derive the SI Units for common and less common physical quantities. This includes:
Acceleration
Velocity
Pressure
Gravitational Constant (G)
Study Tip: Ensure you are practicing the derivation of units for all critical constants, as this guarantees marks.
Fluid Mechanics: Principles and Applications: The MPSC has a strong affinity for Fluid Mechanics principles, especially their engineering and day-to-day uses.
Pascal's Law: Revise the principle and focus on its Applications in hydraulic systems (e.g., hydraulic brakes and lifts).
Bernoulli's Principle: This is identified as a highly probable recurrent topic. Study its Applications in detail, such as its use in aerofoil lift, atomizers, and the functioning of chimneys. Knowing where and how the principle is used is key to cracking MPSC questions.
Student Challenge: I haven't studied P&C properly all year. Should I start a new reference book now?
Authoritative Advice: Absolutely not. The biggest mistake an MPSC Aspirant can make now is introducing new material. Your MPSC Strategy must be based on revision.
Source Confirmation: Stick rigorously to the content you have highlighted in your personal Revision Notes from your original sources (8th, 9th, and 10th State Board or NCERT textbooks).
Focused Revision: Use the list above (Atomic Models, SI Units, Pascal's & Bernoulli’s Applications) as your final P&C checklist. Overlook these topics just once, ensuring immediate recall.
PYQ Linkage: Use your Previous Year Question books to solve only the P&C questions related to these topics immediately after revision. This validates your learning and familiarizes you with MPSC language.
In the highly competitive environment of the MPSC Combined, where cutoffs are unforgiving, every mark is a luxury. The 6 marks from Physics and Chemistry are a golden opportunity that many MPSC Aspirants overlook. By adopting this informed, STI-validated Science Strategy, you are substituting fear with a focused Study Plan. Trust your MPSC Preparation, stick to your core notes, and treat these high-yield topics as your final, unmissable chance to gain an edge.
