The Hong Kong Diploma of Secondary Education (DSE) examination is the main university entrance qualification in Hong Kong. Students typically choose their elective subjects in Form 3 and study them through Form 6. This decision can shape university course options and career directions. Many students feel uncertain about which subjects to pick. This article offers concrete advice based on widely known factors such as university admission requirements, personal interests, and subject difficulty.

Before selecting subjects, students should understand the overall Hong Kong education pathways available after secondary school. These include local universities, self-financing degrees, sub-degree programmes, and overseas study. Each pathway has different subject requirements.

Understand the DSE Subject Structure

The DSE has four core subjects: Chinese Language, English Language, Mathematics, and Liberal Studies (renamed Citizenship and Social Development from the 2024 exam onwards). Students usually take two to three elective subjects from a list of 20 options. The electives are divided into categories:

  • Science subjects: Biology, Chemistry, Physics, Combined Science, Integrated Science
  • Humanities subjects: History, Geography, Economics, Chinese History, Literature in English, Ethics and Religious Studies
  • Business subjects: Business, Accounting and Financial Studies (BAFS), Economics (also listed under humanities)
  • Technology subjects: Information and Communication Technology (ICT), Design and Applied Technology, Technology and Living
  • Arts subjects: Visual Arts, Music, Physical Education (PE is also an elective, not a core)
  • Other subjects: Chinese Literature, Tourism and Hospitality Studies, Health Management and Social Care

Each elective has a specific syllabus and assessment method. For example, Chemistry includes a school-based assessment (SBA) component worth 20% of the final grade, while Economics has no SBA. Students should check the DSE exam format and grading for each subject they consider.

Check University Admission Requirements

Different university programmes require specific subjects. The University of Hong Kong (HKU), Chinese University of Hong Kong (CUHK), Hong Kong University of Science and Technology (HKUST), and other institutions publish subject requirements for each degree. For example:

  • Medicine at HKU requires Biology and Chemistry (or Combined Science with Chemistry and Biology components).
  • Engineering at HKUST requires Mathematics (Compulsory Part) and one science elective, preferably Physics or Chemistry.
  • Law at CUHK has no specific subject requirements but expects high scores in Chinese and English.
  • Business Administration at HKU prefers Economics or BAFS but does not require them.

Students should visit the Joint University Programmes Admissions System (JUPAS) website and read the entrance requirements for their target programmes. The secondary school place allocation process does not directly affect DSE subject selection, but the school's curriculum determines which electives are available.

Weighted Scores and Subject Bonuses

Many universities give extra weight to certain subjects. For example, HKU assigns a bonus factor of 1.5 to Mathematics (Extended Part) for engineering and science programmes. HKUST gives a 1.3 multiplier to Physics and Chemistry for engineering. CUHK offers a 1.2 multiplier to Biology for nursing. These bonuses can raise a student's total score significantly. A student scoring level 5 in Physics with a 1.3 multiplier effectively gets 6.5 points for that subject.

Check each university's official admissions handbook for the latest weighting policies. The information is usually published in October of the year before the DSE exam.

Align Subjects with Your Interests and Strengths

Interest is a strong predictor of sustained effort. A student who enjoys reading history will likely find History easier to study than Chemistry. Conversely, a student who dislikes memorising dates may struggle with History. Take stock of your performance in Form 1 to Form 3 subjects. Look at your report card grades and teacher comments. If you consistently score higher in science than in arts, that is a signal.

Consider taking an online aptitude test. The Hong Kong Education Bureau (EDB) provides a free online tool called the "Career and Life Planning Portfolio" for secondary students. It includes interest and ability assessments. Some schools also offer the Holland Code (RIASEC) test, which categorises interests into six types: Realistic, Investigative, Artistic, Social, Enterprising, and Conventional. For example, a student with high Investigative and Realistic scores may suit science or engineering subjects.

Talk to your subject teachers. They can give specific feedback on your aptitude. For instance, a Physics teacher can tell you whether you grasp concepts quickly or struggle with calculations.

Consider Subject Difficulty and Workload

Some subjects have heavier content or more demanding assessments. For example:

  • Biology: Requires memorisation of many terms and processes. The syllabus covers cell biology, genetics, ecology, and human physiology. Many students find the volume of content challenging.
  • Chemistry: Involves both conceptual understanding and mathematical calculations. The SBA requires lab reports, which can be time-consuming.
  • Physics: Heavy on mathematics and problem-solving. Students weak in math may struggle.
  • Economics: Requires logical reasoning and graph interpretation. Less memorisation than history, but concepts can be abstract.
  • History: Requires essay writing and memorisation of facts and dates. The exam includes data-based questions and essay questions.
  • BAFS: Divided into two streams: Accounting and Business Management. The Accounting stream involves many calculations and rules.
  • ICT: Involves programming, databases, and networking. Practical skills are tested in the exam.

Check the past examination papers and marking schemes on the Hong Kong Examinations and Assessment Authority (HKEAA) website. This gives a realistic idea of the question style and difficulty level. For example, the 2023 DSE Biology paper had a pass rate of about 75% for level 2 and above, while Physics had about 80%. However, these figures vary yearly.

Think About Career Pathways

If you have a specific career in mind, check the subject prerequisites. For example:

  • Architecture: Some universities prefer Visual Arts or Design and Applied Technology.
  • Journalism: No specific subjects, but good Chinese and English are essential.
  • Computer Science: ICT is not always required, but Mathematics (Extended Part Module 2) is often recommended.
  • Nursing: Biology is usually required or preferred.
  • Pharmacy: Chemistry is mandatory at most universities.

If you are unsure about your career, choose subjects that keep options open. A combination of one science, one humanities, and one business subject can cover many university programmes. For example, taking Chemistry, Economics, and Geography allows entry to science, business, and social science programmes.

Remember that many university programmes accept a wide range of subjects. For example, the Bachelor of Social Sciences at CUHK requires only one elective, and any elective is acceptable. The Bachelor of Arts at HKU has no specific subject requirements. So do not feel forced into a narrow set of subjects if you are undecided.

Consider School Subject Availability and Timetable

Not all schools offer all electives. A school with a small Form 3 class may only offer 8 to 10 electives. Check your school's elective list in Form 2 or early Form 3. Some schools have streaming (science stream, arts stream, business stream). If your school streams, you may have to choose between a science block and a humanities block. This can limit your combination. For example, you may not be able to take both Chemistry and History if they are in different blocks.

Talk to the school's academic coordinator or careers teacher. Ask about the timetable constraints. If you want a specific combination, see if it is possible. Some schools allow students to take an extra elective outside school hours through the HKEAA's self-study arrangement. However, self-study requires strong self-discipline and support from parents.

If your school does not offer your preferred subjects, consider transferring to another school. The Direct Subsidized vs Aided Schools article explains the differences between school types. Direct Subsidized Schools (DSS) often have more flexibility in curriculum and may offer a wider range of electives. However, they charge tuition fees ranging from HK$20,000 to HK$80,000 per year.

Consider the Extended Part of Mathematics

Mathematics (Compulsory Part) is taken by all students. There is also an Extended Part (M1 or M2). M1 focuses on calculus and statistics, while M2 focuses on algebra and calculus. Taking the Extended Part is not mandatory, but it is strongly recommended for students aiming at engineering, science, finance, or quantitative fields. Many university programmes in these areas give bonus points for M1 or M2. For example, HKUST engineering gives a 1.5 multiplier to M1 or M2.

However, the Extended Part adds extra lessons and homework. Students who are weak in mathematics may struggle. Only take it if you are confident in your math ability and have a genuine interest. The pass rate for M1 and M2 is around 85% for level 2 and above, but the content is advanced.

Think About the Number of Electives

Most students take two electives. Some take three. Taking three electives can increase your total score for JUPAS, but it also increases workload. The DSE exam period lasts about three weeks. Having three electives means more exam papers. Consider your time management skills. If you are a slow learner, two electives may be enough to achieve high scores. Quality matters more than quantity. A student with two level 5* subjects may have a better chance than a student with three level 4 subjects, depending on the programme.

Check the JUPAS score calculation. Most programmes use the best five subjects (including core subjects) or best six subjects. Some programmes count only four core subjects plus one elective. So having a strong elective is more important than having many electives.

Seek Advice from Multiple Sources

Do not rely solely on one person's opinion. Talk to:

  • Your parents or guardians: They know your habits and strengths.
  • Your class teacher or form teacher: They have an overview of your academic performance.
  • Subject teachers: They know the demands of their subject.
  • Senior students: They have recent experience of the DSE. Ask them about the workload and difficulty.
  • School counsellor or careers teacher: They have resources and information about university requirements.

Attend subject selection talks at your school. Many schools hold information evenings for Form 3 students and parents. These talks explain the elective options and the school's procedures.

If you are considering studying abroad, check the entry requirements of overseas universities. For example, UK universities typically require three A-level subjects, but they accept DSE results. The international school options in Hong Kong article may be relevant if you are thinking of switching to an international curriculum, but that is a separate decision.

Make a Decision and Prepare a Backup Plan

After gathering information, list your top three subject combinations. Rank them by preference. Then, discuss with your parents and teachers. Submit your choices by the school's deadline, usually in March or April of Form 3.

If your first choice is not available due to timetable clashes, have a second choice ready. Some schools allow students to change subjects in the first two weeks of Form 4. If you find the subject too difficult or boring, you can request a change. However, changing subjects later is harder because you miss the first few months of content.

Finally, remember that DSE subject selection is not irreversible. After Form 4, you can switch subjects if the school permits, but it is better to get it right the first time. Use the resources available: the EDB's career planning website, the HKEAA's subject pages, and your school's guidance team. With careful thought, you can choose subjects that match your abilities and goals.
