Chemistry used to feel like a mountain I couldn’t climb — until I started breaking it down topic by topic. This post is my personal roadmap to the chapters that appear most frequently in past-year papers and how I tackled them.
Subtopics & Answers:
Periodic Table and Chemical Properties I explain how I memorized group trends and periodicity using visual mnemonics.
Chemical Bonds and Structures Ionic vs covalent bonds, Lewis structures, and how I used models to understand molecular geometry.
Acids, Bases, and Salts I share how I tackled pH calculations and neutralization reactions with simple analogies.
Electrochemistry and Redox Reactions I break down oxidation numbers, electrochemical cells, and how I answered HOTS-style questions.
Organic Chemistry Basics Naming hydrocarbons, identifying functional groups, and drawing structural formulas — made easy with flashcards.
Tips for answering structured and essay questions I used the CER method (Claim, Evidence, Reasoning) to write clear, logical answers.
