Chemistry

This is a complete, free study companion for Chemistry — built around what the exam actually asks. The topics examiners repeat most are Organic reaction product prediction and multi-step transformations, Coordination chemistry: CFSE, trans effect, ligand substitution, bioinorganic complexes, and Spectroscopy-based structure elucidation using NMR, MS, and UV-visible data. The syllabus runs to 10 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 GATE body, so always confirm the current syllabus and exam dates on the official GATE website before you rely on them.

How to study Chemistry and score well

Start with the highest-frequency topics — In Chemistry, Organic reaction product prediction and multi-step transformations, Coordination chemistry: CFSE, trans effect, ligand substitution, bioinorganic complexes, Spectroscopy-based structure elucidation using NMR, MS, and UV-visible data, and Quantum chemistry: hydrogen-like atoms, operators, angular momentum, model systems 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 GATE 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 10 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: attempting questions they have not truly eliminated options for, spending too long on one hard question, and rushing the sections they know best. Read the whole paper first, bank the marks you are sure of, and come back to the rest.

Manage your time and guess carefully: split your time in proportion to the marks each section carries and keep a few minutes at the end to check. This paper carries negative marking, so attempt a question only when you can rule out at least one or two options — a blind guess costs you marks. Confirm the exact marking scheme for your session on the official portal.
