DSE Revision: Compulsory Part
FoundationThe ICT DSE examines the compulsory part in Paper 1 (multiple-choice and short questions) and the elective modules in Paper 2, plus school-based assessment, with weights per the HKEAA's latest publications. This lesson links the five compulsory areas on a concept map and sets out scoring tactics for MC and short questions and a final-stage revision plan.

§Text Passage
1The ICT examination follows the common structure of Paper 1 on the compulsory part, Paper 2 on the electives, plus school-based assessment: Paper 1 includes multiple-choice and short questions, Paper 2 is answered on the modules the school has taken, and SBA counts coursework during the year. Weights and formats follow the HKEAA's latest publications, so check the current assessment plan before planning revision, lest strategy and format drift apart.
2The compulsory part covers five areas: information processing, fundamentals of computer systems, the Internet and its applications, basic programming concepts, and the social implications of ICT. Rather than re-reading page by page, draw a concept map linking the areas: data representation underpins file organisation, which leads to databases; hardware and software combine into systems; networks join systems into the Internet; social implications close the arc — the whole paper is one connected body of knowledge.
3Multiple-choice questions test fine detail, with options often differing by a single word. Read the stem, circle the key terms, then eliminate the clearly wrong options; for calculations such as file sizes and binary conversion, work out the answer before matching options. Short questions let marks suggest the points: a 2-mark question wants two points and a 4-mark question four; terminology must be exact — write primary key rather than the most important field, for marks follow key terms.
4In the final stretch, let past papers lead: sit recent papers first to find weak areas, return to notes for those areas, then rehearse under timed conditions. For example, if binary conversion keeps failing, drill ten similar questions until the steps are automatic. In the last week, review the concept map and the mistake book instead of chasing new problems, keep regular hours, and walk into the hall in a steady state.

3Step by step Steps
- Step 1: Know the assessment structureRevision strategy starts with seeing the examination itself. The ICT DSE sets Paper 1 on the compulsory part with multiple-choice and short questions, Paper 2 on the electives according to the modules the school has taken, and school-based assessment counting coursework. For example, a candidate who overweights multiple choice and abandons short questions will fall where marks are rich. Check the HKEAA's latest assessment plan at the start of the year and allocate revision time by it.
- Step 2: Weave the five areas into a concept mapThe compulsory part covers five areas: information processing, fundamentals of computer systems, the Internet and its applications, basic programming concepts, and social implications. Connect them on a concept map: data representation underpins files and databases; hardware and software form systems; networks join systems into the Internet; social implications conclude. For example, answering why online banking needs encryption draws on protocols, data security and social implications at once — the map speeds the recall.
- Step 3: Tackling multiple-choice questionsMultiple-choice items test detail; options differ by a word. The routine: read the stem and circle key terms, identify the concept tested, eliminate clearly wrong options, then check the survivors against definitions. For example, asked for the properties of a primary key, options saying it may repeat or be empty are eliminated at once, and the rest is checked against unique and non-empty. For calculations — file sizes, binary conversion — set out the working first, then match options; never test each option in turn.
- Step 4: The scoring logic of short questionsShort questions map marks to points: about two points for two marks, four for four; extra irrelevant writing earns nothing and wastes time. Answer with a conclusion sentence first, then expand point by point with exact terminology. For example, comparing sequential and random files demands point-by-point contrast of access method and suitable use, using terms such as linear search and direct access; colloquial paraphrases, however correct in spirit, lose the final mark — the commonest loss in short questions.
- Step 5: A frame for data and application questionsThe compulsory paper often sets data questions: one or two contextual materials, asking to identify problems, explain effects or suggest measures. The frame has three steps: name the concept involved, such as the digital divide or privacy; quote specific details from the materials; then answer the question verb — if it says suggest, give a workable measure and say why it works. For example, with materials on seniors unable to book online, write the term digital divide, quote the usage-rate detail, and propose training or retained counters.
- Step 6: Danger spots in calculation questionsCalculation questions cluster in data representation and file sizes, with three danger spots: unit conversion (bits and bytes, KB and MB), place values in binary and hexadecimal conversion, and pixels and colour depth in the image formula. For example, computing a 1024×768 image: multiply pixels, multiply bytes per pixel, divide by 1024 twice for MB — a missed step loses everything. Drill ten questions per type and fix the steps into a template, so the exam becomes filling numbers into a familiar grid, fast and safe.
- Step 7: The final-stage revision rhythmThe final phase follows past papers and weak areas: finish recent papers, tabulate losses by area, revisit the two weakest areas in notes, and rehearse the rest under the clock. For example, if data questions keep missing the quotation of materials, drill five similar questions until name the concept, quote the material, answer the verb becomes reflex. In the last week, review lightly with the concept map and mistake book, touch no new problems, keep ordinary hours — steady performance beats last-minute gambles.
5Worked example Example
Dissecting a typical compulsory long question: A school records homework defaults in spreadsheets kept by each teacher separately; the same student's data keeps repeating in different versions. The school considers a database. (a) Identify one problem with the spreadsheet approach and explain it; (b) explain how a database solves the problem; (c) apart from technical issues, name one social issue to note when introducing it. List the answer points and marking positions.
- Read: (a) asks problem plus explanation, (b) asks how it is solved, (c) asks a social issue — answer in parts matched to marks, not one blended paragraph
- Marking points for (a): name data redundancy — the same student repeated across files — and explain that differing versions mean inconsistency; vague words like messy miss the key terms
- Marking points for (b): centralised storage with data held once; a primary key identifying each record; the DBMS controlling access rights and integrity so teachers share one version
- Marking points for (c): teacher training for differing digital skills, protection of students' personal data and privacy, or access rights — tie the issue to the scenario, not in the abstract
- General rule: the marking positions are key terms hit, explanation tied to data, issue tied to context — self-check revision against all three
- Answer: (a) The problem is data redundancy: each teacher keeps separate files, so the same student's data repeats across files; updates missed in one copy create inconsistency — the differing versions in the stem. (b) A database centralises student data in one table, with the student ID as primary key uniquely identifying each record; teachers reach the same data through the DBMS, which also sets access rights and integrity checks to keep data consistent and reliable. (c) On introduction, the school must train teachers for differing ICT skills, and since default records are personal data, rights must be set and privacy properly protected. Marking points: (a) naming redundancy and inconsistency, (b) centralised storage plus primary key plus rights, (c) issues tied to the scenario — missing any part loses its marks.
