- Only certain calculators are permitted in the exam venue, so make sure you’re getting the correct one, or you could be left in the dust

Candidates taking the Hong Kong Diploma of Secondary Education (HKDSE) Examination know that being well-prepared is halfway to success. But did you know that good preparation for acing the exam also includes getting the essential equipment, such as a calculator, ready?
Good results for the HKDSE exam matter to all candidates - their prospects for their university education and future careers are at stake. No candidate wants a faulty calculator to affect their performance at the exam venue.
Many a student has heard about unlucky, calculator-related incidents that have occurred at exam venues. Here are a few handy tips to ensure this sort of mishap does not happen to you.
DSE perfect scorers share their university plans
Check your calculator
You cannot use just any calculator at the exam venue. The Hong Kong Examinations and Assessment Authority (HKEAA) stipulates that, except for exams for language subjects, candidates should bring and use only the electronic calculators that meet its exact requirements. These include CASIO Scientific Programmable FX-50FHII and FX-3650PII calculators. Permitted calculators are pad-printed with the “H.K.E.A.A. APPROVED” or “H.K.E.A. APPROVED” labels. Candidates will face marks deduction if they use calculators without these labels.
Take a spare
No matter the price or multiple powerful functions a calculator has, if it fails to perform at a public exam, it’ll be a disaster for the candidate. The winning strategy for smart candidates is to take a spare permitted calculator and ensure it’s ready at the exam venue.
Check it in advance
Before the exam, savvy candidates should check their calculators carefully to make sure they are stable and in top form and do not make any calculation mistakes. No spare calculators are available for loan at the exam venues. Exam officers and invigilators will not provide any assistance to candidates whose calculators fail to function properly, nor is there any special, compassionate treatment for the affected exam papers. Therefore, packing a spare permitted calculator for the exam is absolutely essential.
