Chemistry

This is a complete, free study companion for Chemistry — built around what the exam actually asks. The topics examiners repeat most are Chemical Bonding & Molecular Structure, Thermodynamics & Equilibrium, and Electrochemistry. The syllabus runs to 27 chapters. Below you'll find the full topic-frequency ranking, the exam paper pattern, every chapter, a step-by-step study plan, and the official downloads — everything in one place.

Everything here is free. We're an independent student resource, not the official CET body, so always confirm the current syllabus and exam dates on the official CET website before you rely on them.

How to study Chemistry and score well

Start with the highest-frequency topics — In Chemistry, Chemical Bonding & Molecular Structure, Thermodynamics & Equilibrium, Electrochemistry, and Chemical Kinetics appear again and again in past papers. Master these first — they return the most marks for the time you put in.
Practise with previous-year papers — Solve the last 5–10 years of CET Chemistry papers under timed, exam-like conditions. Past papers show exactly which topics repeat and how questions are worded.
Revise actively, not passively — Write a one-page summary for each of the 27 chapters — key definitions, formulas and the points examiners reward — then re-test yourself instead of re-reading.
Mark your answers with the official scheme — After each practice paper, score yourself against the official marking scheme. It shows how marks are awarded step-by-step, so you learn to present answers the way examiners expect.

Exam tips: how to score higher in Chemistry

Where students lose marks: spending too long on one hard question, second-guessing answers they knew, and never practising full papers under time. Read the whole paper mentally as you go, bank the questions you are sure of first, and keep moving.

Attempt everything: MHT-CET and KCET carry no negative marking, so a blank answer is the only guaranteed zero. Eliminate what you can and answer every question — then confirm the current marking scheme for your session in the official brochure.
