What is AP EAPCET Chapter-Wise Weightage?

AP EAPCET Chapter-Wise Weightage shows the typical number of questions from each chapter in Physics, Chemistry, and Mathematics, helping students prioritise high-impact topics.

For example:

• In Physics, Thermodynamics, Work & Energy, Laws of Motion, and Rotational Motion are heavily weighted.
• For Chemistry, the chapters of Atomic Structure, Chemical Bonding, Solutions, Organic Chemistry, and Electrochemistry carry most questions.
• In Mathematics, chapters like Probability, Vectors, Calculus, Coordinate Geometry, Algebra, and Trigonometry contribute the most to the exam.

Knowing the chapter-wise weightage allows candidates to prioritize high-impact chapters, plan their revision efficiently, and improve their chances of scoring well.

AP EAPCET Chapter-wise Weightage Overview

AP EAPCET Physics Chapter-Wise Weightage:

In AP EAPCET Physics, chapters tied to Mechanics and Thermodynamics often dominate the question distribution.

• Thermodynamics alone typically contributes around 9 % of the questions, making it the single highest-weight chapter.
• Work, Energy & Power and System of Particles & Rotational Motion carry about 5–6% weight each.
• Laws of Motion, Motion in a Plane, and Moving Charges & Magnetism contribute around 4–6% each.
• Chapters like Oscillations, Gravitation, Current Electricity, Waves, and Electrostatics have moderate weightage of 3–4% each.

AP EAPCET Chemistry Chapter-Wise Weightage:

• Organic Chemistry, Chemical Bonding, Atomic Structure, p-Block, d- & f-Block, Coordination Compounds, Solutions, and Thermodynamics are high-weight chapters.
• Hydrocarbons, N-Compounds, Biomolecules, Polymers, and Electrochemistry carry moderate weight.
• Surface Chemistry, Metallurgy, States of Matter, and Environmental Chemistry are low-weight but can be rank-deciding.

• Organic Chemistry: Focuses on memorizing patterns and reactions.
• Inorganic Chemistry: Demands remembering concepts like chemical bonding and periodic trends.
• Physical Chemistry: Emphasizes problem-solving, requiring practice to tackle numerical questions efficiently.

More stress should be given on Organic Chemistry, its structures and reactions. You may be asked to also remember the reagents and specific temperatures. This section involves a lot of memorization and therefore you must regularly go through the Organic Chemistry section.

AP EAPCET Mathematics Chapter-Wise Weightage:

• Algebra (~28–29%) is the most important, covering Binomial Theorem, Matrices, and Permutations & Combinations.
• Probability (~14–15%) and Vectors & Coordinate Geometry (~10–11%) are high-weight.
• Calculus & Trigonometry (~8–10%) are significant; other chapters carry 1–5%.

Biology Chapter-wise Weightage

In the AP EAPCET 2025 Biology exam:

• 80 questions are divided equally between Zoology and Botany, certain chapters carry higher weightage.
• In Zoology, highlights Human Physiology (~20%), Genetics & Evolution (~18%), and Microorganisms & Disease (~12%), with Human Health and Environmental Biology ~10% each. Botany emphasizes Plant Physiology (~22%) and Ecology & Environment (~15%), with Plant Classification and Plant Diseases contributing less.

ZOOLOGY:

• Human Physiology having the Chapter of Digestion, Respiration and Excretion have the highest weightage of 20%.
• Candidates should know the diagrams by heart along with the pathways involved.
• MCQs from the chapter of microorganisms and diseases are easy to score, if known the exact correct answer, is about 22%.
• Genetics involving Mendelian crosses and evolutionary theories, although containing readable concepts, are high scoring, containing 18% weightage.

BOTANY:

• Plant Physiology in the Botany section, carries the most weightage of 22%. Students should cover the chapters of Photosynthesis along with C3, C4 plants, along with Transport in plants which is an easier concept.
• Taxonomy and writing of scientific names of 8% share, must be specifically noted along with their classification systems.
• Plant diseases and pest control has a lower weightage of 8% and can be understood later.

Biotechnology and Genetic Engineering:

• The section of Biotechnology and Genetic Engineering has the least weightage of 17% among all three sections in Biology in the AP EAPCET exam.
• Biotechnology applications, focusing on cloning, agriculture and plasmids have heavy weightage and will help students in their future endeavours.
• Structure of DNA and Recombinant DNA Technology and their applications will help candidates delve deeper into the topic and understand better of the topic.
