Cambridge IAL Computer Science exam-day guide
Cambridge IAL Computer Science · Prepare for the day ahead.
Your checklist
Photo ID and statement of entry
Bring the identification your centre requires (usually a passport or national ID) plus your candidate statement of entry or timetable slip. Exact accepted ID and whether a digital copy is allowed vary by centre, so confirm with your exams officer in advance.
Black pens (at least two) plus pencil, eraser, sharpener
Written papers require black or dark blue ink. Keep a spare pen and a pencil for any diagrams, tables or rough work. Do not rely on a single pen.
Clear pencil case or transparent bag
Many centres require a see-through case so invigilators can check contents quickly. If your centre has a specific rule, confirm with the provider.
Approved calculator
Check which calculator model your centre permits and whether the memory must be cleared. For Computer Science papers a calculator is rarely needed, but confirm the subject-specific rule with your teacher or exams officer rather than assuming.
No smart devices on your person
Mobile phones, smart watches and any wearable with communication or storage capability must be switched off and left outside the exam room as directed. Leaving one in a pocket can lead to malpractice proceedings even if unused.
Know your candidate number and centre number
You will write these on every answer booklet and any loose sheets. Practise writing them cleanly so you do not lose time or mislabel a script.
Confirm the paper code and duration
Cambridge IAL Computer Science has multiple components with different lengths and weightings. Check the exact paper code, date, start time and duration on your statement of entry and confirm any ambiguity with your exams officer.
Plan arrival with buffer time
Arrive well before the scheduled start so you can be seated and checked in. Late arrival rules are set by the centre and Cambridge; confirm the cut-off with the provider rather than guessing.
Water in a plain transparent bottle, label removed
Many centres allow this, but rules differ. Confirm with the provider whether drinks are permitted in your exam room.
Revise from your own notes and past-paper mark schemes
In the final days, focus on command words, mark allocation and the specific topics you keep losing marks on. Do not try to learn brand-new content in the last 24 hours.
Know the misconduct rules before you sit
Read your centre's notice to candidates so you understand what counts as malpractice, including bringing unauthorised material or communicating with another candidate.
Sleep, food and a calm routine
A normal night's sleep and a proper meal do more for recall than a late-night cram. Set two alarms and lay out your materials the night before.
Plan the day
Do a timed past paper under exam conditions for each remaining component. Mark it honestly against the mark scheme, list every lost mark by topic and command word, and rank those topics by how often they appear. Spend the remaining time on the top three weak areas only. Confirm your seat, start time and room with your exams officer, and check that your ID and calculator meet the centre's rules.
Review your condensed notes on the highest-weight topics: for Computer Science these typically include data structures, algorithms and complexity, programming paradigms, databases and SQL, networking, and hardware/software fundamentals. Rehearse the standard answer structures for common question types, such as explaining the purpose of a protocol layer, tracing an algorithm, writing pseudocode, or comparing two approaches with a justified conclusion.
Do light revision only: skim your error log, key definitions and any pseudocode conventions your syllabus uses. Pack your bag with ID, statement of entry, pens, pencil, calculator and clear case. Check the journey and set alarms. Stop studying early enough to sleep properly; do not start a new topic.
Eat a proper breakfast, arrive early, and avoid discussing content with other candidates in case it unsettles you or breaches rules. Switch off and hand in your phone as directed. Once seated, read the front of the paper, check the number of pages and questions, and note the marks per question.
Read the instructions and the whole paper briefly. Allocate time roughly in proportion to marks, leaving a few minutes to check. Start with a question you can answer confidently to settle nerves, but do not spend too long on any single part.
Answer the question as asked, matching the command word: state, describe, explain, compare, evaluate. Show working for algorithm traces and calculations. Use technical vocabulary precisely. If a question is worth several marks, give that many distinct points rather than one long sentence. If you get stuck, move on and return later.
Check that every question has been attempted, that your candidate and centre numbers are on all booklets and loose sheets, and that diagrams are labelled. Correct any answer you have changed clearly rather than leaving two versions. Use remaining time to add precise detail to weak answers.
Rules to check
Bring only permitted items into the exam room. Any unauthorised material, including notes, phones or smart watches, must be left outside as directed; possession can be treated as malpractice even if you did not use it.
Follow all invigilator instructions and remain silent from the moment you enter until you leave. Do not communicate with other candidates in any way during the exam.
If you need to leave the room, raise your hand and wait for an invigilator. Rules on supervised toilet breaks and whether extra time is granted vary, so confirm the arrangement with the provider before exam day.
Write in black or dark blue ink, keep your handwriting legible, and cross out work you do not want marked. Label any additional sheets and fasten them as instructed.
If you believe there is an error in the paper, or you are affected by illness or disturbance, tell the invigilator immediately and ensure it is recorded; report it to your exams officer afterwards so the centre can apply the proper procedure.
Do not remove any exam material, including question papers and rough work, unless the invigilator explicitly permits it.
Scoring is by mark scheme: marks are awarded for specific, relevant points, so answer the command word and give enough distinct points for the marks available. Method marks may be available even when the final answer is wrong, so always show working.
Results, grade boundaries and any post-exam enquiries about scripts are handled through your centre. Confirm deadlines and procedures with the provider rather than relying on rumour.
