5-Min DSE Biology 生物科 Practice

Revise DSE Biology with 1,400 multiple-choice questions in English and Traditional Chinese. Choose a topic, select an answer and check the explanation. Cells, genetics, ecology and data analysis sit alongside dedicated practice in photosynthesis, respiration, digestion, circulation and movement. TOPIC PRACTICE The 25 categories separate concepts that need different practice: molecules and food tests; diffusion, osmosis and active transport; enzymes; gas exchange; plant transport; cell division; DNA and gene expression; inheritance; reproduction; evolution; nervous and hormonal coordination; health and immunity; scientific investigation; and the four elective areas. Bones, joints and muscles have their own topic, including tendons, ligaments, joint types and antagonistic action. STANDALONE QUESTIONS Each question can be answered on its own. Practice spaces related concepts when alternatives are available, instead of keeping a long sequence tied to one case. A smaller set of investigation questions supplies the necessary measurements or results table in the question itself: microscopy, catalase, potometers, quadrats, water balance and PCR among them. MULTIPLE-CHOICE ANSWERS Every task uses selectable answers. Some ask for a correct fact; others ask which statement is incorrect or which combination of claims is supported. Calculation tasks give numerical choices with units, so you can work out a magnification, rate, percentage or genetic probability without typing a response. Explanations identify the relevant process and correct common misconceptions. Diagram and graph MCQs cover cells, vessels, classification and experiments. OBSERVATION VERSUS MECHANISM Explanations keep what the results show apart from why it happens. A potometer measures uptake rather than water loss, a probability within one group of offspring is not a share of all offspring, and in ecology cases two variables changing together do not prove cause. DIFFICULTY THAT MATCHES THE TASK Easy questions are recognition, such as naming an organelle or spotting the independent variable. Medium questions apply a concept or ask for a calculation. Hard questions compare several scientific claims and distinguish sound reasoning from a plausible misconception. ILLUSTRATED STUDY NOTES Twelve chapters open with the exam format and a study cycle, then give each topic an illustration, key ideas, a comparison table, a worked investigation, a common-confusion warning and a recall question, covering pairs such as diffusion and osmosis or magnification and resolution. Read a chapter, answer its recall question from memory, then practise that topic. TIMED SETS AND REVIEW A timed set gives you 30 questions in 35 minutes, with a built-in calculator for magnifications and percentages. Fifteen correct, or 50%, is the app's own practice target rather than any exam body's pass mark. Wrong answers collect in the mistake book until you get them right; bookmarks keep questions to revisit, and personal notes record slips such as forgetting to convert millimetres to micrometres. TWO LANGUAGES, OFFLINE Set the interface and question language separately to English or Traditional Chinese, so a term like transpiration can be checked in either language. Questions, notes and illustrations are stored on the device, so biology revision works offline. PREMIUM The first 100 biology questions are open to everyone. Premium opens all 1,400 and removes ads, as a lifetime unlock or a 12-month or 3-month plan; the two plans renew automatically until cancelled in your store account. Astera Technology Limited publishes this app independently; it is not affiliated with or endorsed by the HKEAA, the EDB or any examination body. Every question, results table and explanation is original practice material, not an official question or a past paper.
