How do you check a DSE calculator? Functions to master and how to prepare before the exam
Calculators are allowed in the HKDSE Mathematics papers (including Extension Module 1 and Module 2), but the HKEAA has clear rules on which calculator models may be used. Candidates should check the latest list on the HKEAA website themselves around the time of registration, and should not rely on old information or on what others say. When checking, look at the full model number, because with the same brand one model may be approved and another may not. In the weeks before the exam, practise on your own calculator: basic operations, converting between fractions and decimals, angle settings, statistics functions and so on, and practise finishing questions within the time limit to reduce the chance of pressing the wrong key. In addition, the calculator must carry a "H.K.E.A. APPROVED" or "H.K.E.A.A. APPROVED" label, and candidates should use the same calculator throughout their revision so that their operating habits stay consistent.

- The calculator models allowed in the HKDSE are those published by the HKEAA, and candidates should check for themselves.
- Check the full model number; under the same brand, different models may be treated differently.
- Before the exam, practise on your own calculator the functions you commonly use, such as fractions, angles and statistics.
- Tutoring comes in many forms; when choosing, consider learning needs rather than comparing prices alone.
Why you should check the calculator model yourself
Every year the HKEAA publishes a list of calculator models that may be used in each HKDSE subject. The list may be updated, so candidates should not rely on information from several years ago, nor only on what classmates or tutors say. The safest approach is to check the latest "approved calculator models" list on the HKEAA website and to treat that list as authoritative. Besides being on the list, the calculator must also carry a "H.K.E.A. APPROVED" or "H.K.E.A.A. APPROVED" label; otherwise marks may be deducted.
When checking, pay attention to the full model number, including any letters or numbers after it. Under the same brand, models that look similar may be treated differently, so remembering only the brand name is not enough. If you are unsure about a model, ask the HKEAA directly rather than guessing.
Candidates should also keep the calculator's manual and confirm before the exam that the calculator works properly. If a calculator breaks down on the exam day, the exam venue will generally follow set procedures, but candidates should not assume a calculator can be borrowed. It is best to bring your own backup calculator that meets the rules.
Calculators are allowed in the HKDSE Mathematics papers and in Extension Module 1 and Module 2, but the papers rely on calculators to different degrees. Candidates should check, according to the combination of subjects they are sitting, that their model meets the rules for all the relevant subjects.
Calculator functions to master before the exam
Calculators differ between models, but the following kinds of operation are often used in HKDSE Mathematics, and candidates should practise each one on their own calculator: the four basic operations and brackets, converting between fractions and decimals, percentage calculations, switching between degrees and radians, trigonometric and inverse trigonometric functions, logarithms and exponents, square roots and powers, statistics functions (mean, standard deviation and so on), and the memory function.
Candidates should also be familiar with clearing the screen, correcting input errors and switching between modes. Exam time is tight, and it is a pity to waste time because you are unfamiliar with the keys. When working through past papers or mock papers, use the same calculator throughout so that your fingers get used to where the keys are.
COMP is the basic calculation mode on many calculators and has nothing to do with graphing or symbolic operations. Candidates may use only models on the list and should not try to modify their calculator or use unapproved programs; the HKEAA states that bringing an unapproved calculator with removable stored data can lead to disqualification from the entire exam.
If you are sitting several elective subjects, check that your calculator is suitable for all of them, so that you do not slip up in the exam because of extra restrictions in a particular subject.
Calculators, revision and tutoring
A calculator is only a tool; understanding mathematical concepts still matters most. If you find you often rely on the calculator for steps you should be able to do mentally or on paper, check whether you are not yet fluent in the topic concerned. During revision, put the calculator away first and do some questions by hand, then use the calculator to check your answers.
Many parents consider tutoring for their children. Common forms include tutoring centres, private tutoring, home tutoring and online tutoring. Each has its own features: tutoring centres usually teach in small groups, private tutoring can target individual weaknesses, home tutoring saves travelling time, and online tutoring is more flexible about time and place. When choosing, consider your child's learning needs, the tutor's teaching style and the family's schedule, rather than comparing prices alone.
Whether or not you have tutoring, candidates should get into the habit of checking official information themselves, including the calculator model list and the exam rules. Advice from tutors or classmates can be a reference, but the HKEAA's published information is what counts in the end.

Calculator habits from primary to secondary school
Calculators are generally not needed at primary level, where the focus is on building mental and written calculation skills. In junior secondary, students begin to handle more complex calculations and can learn the basic functions of a calculator under parental guidance, but they should not come to depend on it too early. At senior secondary, especially when preparing for the HKDSE, students should systematically become familiar with an approved calculator model.
Parents can help their children get into the habit of checking the calculator, for example confirming the night before the exam that the battery is full and the keys work, and putting a backup calculator in the school bag. These small steps reduce last-minute panic on the exam day.
If your child is in primary school, you can refer to the key points of the P1 to P6 maths topics to see which basic skills should be consolidated first, before gradually introducing the calculator as an aid.
Matching calculator operations to common topics
Different HKDSE Mathematics topics rely on the calculator to different degrees. For example, when working with standard deviation (SD), candidates should be familiar with the calculator's statistics mode and know how to enter data and read the mean and standard deviation; at the same time they should understand what standard deviation means, so that they can do more than press keys without being able to explain the result.
At primary level, calculation skills are built mainly through mental and written work, and parents should not let children use a calculator in place of basic calculation too early. At senior secondary, a calculator can help with lengthy numerical work, but candidates must still grasp the steps and principles of the calculation and should not treat the calculator as a shortcut.
Candidates can refer to the key points of the S4 and S6 maths topics and organise calculator steps by topic, for example practising entering data in statistics topics and switching angle settings in trigonometry topics, so that calculator practice and understanding of the topic deepen together.
Frequently asked questions
Where can I find the calculator models allowed in the HKDSE?
Candidates should check the latest list of calculator models allowed in the HKDSE on the HKEAA website. The list may be updated from time to time, so the HKEAA's announcement for the current year is what counts; do not rely on old information or on what others say. The calculator must also carry a "H.K.E.A. APPROVED" or "H.K.E.A.A. APPROVED" label. If you have any questions, ask the HKEAA directly.
What should I do if my calculator breaks down on the exam day?
Exam venues generally have set procedures for handling calculator breakdowns, but candidates should not assume a calculator can be borrowed. The safest approach is to bring your own backup calculator that meets the rules and works properly, and to check the battery and keys before the exam.
Should I take tutoring to prepare for Mathematics?
Whether to take tutoring depends on individual needs. Common forms include tutoring centres, private tutoring, home tutoring and online tutoring, each with its own features. Candidates should first understand their own weaknesses, then consider the tutor's teaching style, scheduling and the family's budget, rather than comparing prices alone.
What use is the calculator's statistics function in HKDSE Mathematics?
The calculator's statistics function can be used to calculate the mean, standard deviation and so on, but candidates must first understand what these statistics mean and be familiar with the steps for entering data and reading the results. The operations differ between models, so practise repeatedly on your own calculator.
Should primary school students use calculators?
Calculators are generally not needed at primary level, where the focus is on building mental and written calculation skills. Parents can let children learn the basic functions of a calculator in junior secondary under their guidance, but children should not come to depend on it too early.
Are calculators allowed in HKDSE Mathematics?
Calculators are allowed in the Hong Kong Diploma of Secondary Education (HKDSE) Mathematics papers and in Extension Module 1 and Module 2, but the model must be on the list published by the HKEAA and must carry a "H.K.E.A. APPROVED" or "H.K.E.A.A. APPROVED" label. Candidates should rely on the HKEAA's latest announcement.
