Important Chapters of Physics

Here we are going t mentions some of the most important physics topics which must be covered if you are preparing for CAPF Paper-I: Magnet, electricity, light, sound, work and energy, gravitation, Force And Laws Of Motion, Motion, Chemical Effects Of Electriccurrent, Sound, Friction, Force and Pressure, Electronic Current and its effects, Motion and Time, Heat, etc.

At the beginning of your preparation, you should start them with the NCERT books mentioned above in the article so that you can recall your knowledge as well as you can learn the basics very quickly and smoothly.

Important Chapters of Chemistry

As for the Chemistry, the most notable which should be covered first are: Acids, Bases and Salts, Physical and Chemical Changes, Synthetic Fibres And Plastics, Materials Metals And Non-Metals, Coal And petroleum, Combustion And Flame, Matter In Our Surroundings, Is Matter Around Us Pure, Atoms And Molecules, Structure Of The Atom, Chemical Reactions and Equations, Acids, Bases and Salts, Metals and Non-metals, Carbon and its Compounds, Periodic Classification of Elements, etc.

UPSC, the conducting board of CAPF AC, tends to ask questions more theoretical based. Therefore, one needs to gain a very good conceptual understanding of Science, especially chemistry. They often go into very minute details like chemical formulas, reactions, etc. Still, don’t waste much time. You just need basic science concepts, principles and their day-to-day application clear.

Important Chapters of Biology

Here is a list of important topics from which UPSC asks questions almost every year: Nutrition in Plants, Nutrition in Animals, Respiration in Organisms, Transportation in Animals and Plants, Reproduction in plants, Microorganisms Friend And foe, Cell Structure And Functions, Reproduction In Animals, Reaching The Age Of Adolescence, The Fundamental Unit Of Life, Tissues, Diversity In Living Organisms, Why Do We Fall ill, Life Processes, Control and Coordination, reproduction, evolution, the human eye, Biotechnology Principle and Processes, Biotechnology and its Applications, etc.

Biology is an important part of science. Current affairs on cells, diseases, neuro, biotechnology is really worth time spending. Finish up biology in 2 - 3 months while continuing other sections.

Preparation from Current affairs and Other sources

Current affairs is surely an important part of science. From current affairs each year almost 15-20 questions can be expected among which 4-5 questions can be from science. So, while following up on current affairs, environmental changes, climate change, environmental distractions, new diseases like COVID-19, etc. has an immense amount of chances to occur.
