About this app

DSE Chemistry Review is a study app designed for the Hong Kong Diploma of Secondary Education Examination (HKDSE) Chemistry subject. It combines key notes, practice questions, and vocabulary cards for fifteen topics in one place, allowing for offline review anytime.

Why Use This App?

The app aligns its topics with publicly available chemistry curriculum and assessment guidelines. All questions are original and include explanations, showing you why you got them right or wrong.

- 710 practice questions, each with an explanation

- 370 vocabulary cards to help you recall definitions, symbols, and proper nouns

- 15 key notes, one page per topic

- Customizable quizzes, allowing you to choose topics and number of questions, with countdown timers

- Incorrect questions are automatically categorized, allowing you to focus on weaker topics

- Clear overview of your mastery level for each topic

One-click switching between English, Traditional Chinese, and Simplified Chinese

Many students understand concepts in Chinese but answer in English, resulting in lost points due to mismatched terminology. Every question, explanation, and vocabulary card in this app is available in three languages, which can be switched with a simple tap on the homepage: first, use the language you're familiar with to understand the concepts, then switch back to English to check how the terminology is spelled.

Covering Fifteen Topics

The compulsory section includes twelve topics that everyone must read:

- Earth: Atmosphere, Oceans, Rocks, and Minerals

- The Microscopic World I: Atomic Structure, Periodic Table, Metallic Bonds, Ionic Bonds, and Covalent Bonds

- Metals: Occurrence and Extraction of Metals, Metallic Reactivity Series, Reaction Quality, Corrosion and Protection

- Acids and Bases: Indicators and pH, Strong Acids and Strong Bases vs. Weak Acids and Weak Bases, Salts and Neutralization, Volumetric Analysis

- Fossil Fuels and Carbon Compounds: Hydrocarbons, Homologous Series and Nomenclature, Alkanes and Alkenes, Addition Polymers

- The Microscopic World II: Molecular Polarity, Intermolecular Attraction, Structure of Ice, Shapes of Simple Molecules

- Redox Reactions, Chemical Cells, and Electrolysis: Oxidation and Reduction, Chemical Cells, Electrolysis

- Chemical Reactions and Energy: Energy Changes in Reactions, Standard Enthalpy Change, Hess's Law

- Reaction Rate: Measurement of Rate, Factors Affecting Rate, Molar Volume of Gases

- Chemical Equilibrium: Dynamic Equilibrium, Equilibrium Constant, Shift of Equilibrium Positions

- Chemistry of Carbon Compounds: Isomerism, Typical Reactions of Various Functional Groups, Important Organic Substances

- Laws in the Chemical World: Periodic Variations, Oxides of Various Elements, Properties of Transition Metals

The elective section includes all three topics, ensuring no student misses any of the two courses chosen by their school:

- Industrial Chemistry: Industrial Processes, Rate Equations, Activation Energy, Catalysis, Green Chemistry

- Materials Chemistry: Natural and Synthetic Polymers, Plastics, Metals and Alloys, Modern Synthetic Materials

- Analytical Chemistry: Detection of Chemical Species, Separation and Purification, Quantitative Analysis, Instrumental Analysis Methods

Understand First, Then Master the Exercises

Each topic begins with a page of key notes, listing main concepts, keywords, and common mistakes. After reading, you can jump directly to the exercises for the same topic. This is a review tool, not a mock exam, so there is no passing score; it only reflects your level of mastery for each topic, letting you know which lesson to focus on next.
