Today, let’s systematically analyze the Chemistry section of the CSCA exam 👇
1️⃣ What is the Chemistry subject?
CSCA Chemistry is designed to assess the core chemistry competencies international students need for science and engineering programs at Chinese universities, including:
-
Understanding of basic chemistry concepts
-
Calculation and logical reasoning skills
-
Experimental analysis and application ability
⏱ Duration: 60 minutes
📈 Total score: 100 points
📄 Question type: Single‑choice questions (48 questions in total)
🌐 Language: Chinese / English (depends on the program)
🧪 Format: Standardized national exam
2️⃣ Four core modules
1. Basic Chemical Concepts and Calculations
-
Classification of substances, changes of state
-
Chemical equations, basic chemical terminology
-
pH, solution concentration calculations
-
Amount of substance (n = m/M), ideal gas law
👉 Tests whether your foundation is solid and formulas are correctly applied.
2. Properties of Substances and Chemical Reactions
-
Properties of common inorganic substances (acids, bases, salts, oxides)
-
Hydrocarbons and common organic derivatives
-
Redox reaction identification
-
Methods for testing common ions
👉 Multiple‑choice questions often combine “properties + reaction rules”.
3. Chemical Theories and Principles
-
Atomic structure, periodic trends
-
Chemical bonds, intermolecular forces
-
Reaction rates and chemical equilibrium
-
Electrolyte solution theory
👉 Tests understanding, not rote memorization. Many questions ask: “Which option is more reasonable?”
4. Chemical Experiments and Practical Applications
-
Lab safety, basic instruments
-
Preparation and testing of common gases (H₂, CO₂, O₂, etc.)
-
Separation and purification (distillation, filtration, extraction, sublimation)
-
Basic industrial processes (e.g., ammonia synthesis)
👉 High proportion of scenario‑based questions; diagram questions are common.
3️⃣ Difficulty analysis
The exam has 48 questions with a 60‑minute time limit. You need both speed and accuracy.
Difficulty level is between high school chemistry and introductory university chemistry. The scope is broad, but there are no overly difficult or strange questions.
⚠️ Students with weak chemistry foundations often lose points on Chinese terminology and calculation problems.
⚠️ The difficulty is not in the depth of knowledge, but in the large amount of information in each question and the wide logical leaps required to solve them.
4️⃣ Tips for preparation
To prepare for CSCA Chemistry:
-
Memorize elemental equations and thoroughly understand basic concepts
-
Practice past exam papers and summarize experimental question patterns
-
Use example questions to consolidate common weak points
