Chemistry

This is a complete, free study companion for Chemistry — built around what the exam actually asks. The topics examiners repeat most are VSEPR theory and molecular geometry, Lewis structures and electron-dot formulae, and Ideal gas equation PV = nRT numerical problems. The syllabus runs to 6 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 Maharashtra Board body, so always confirm the current syllabus and exam dates on the official Maharashtra Board website before you rely on them.

How to study Chemistry and score well

Start with the highest-frequency topics — In Chemistry, VSEPR theory and molecular geometry, Lewis structures and electron-dot formulae, Ideal gas equation PV = nRT numerical problems, and Hess law and enthalpy cycle calculations 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 Maharashtra Board 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 6 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: rushing the high-weightage questions, skipping the steps the marking scheme rewards, and saving easy sections for last. Read the whole paper first, attempt your strongest section early to bank marks, and always show your working.

Manage your time: split your time in proportion to the marks each section carries, keep a few minutes at the end to check, and never leave a question blank — a partial, structured answer still earns partial marks.
