MATSEC IM Computing exam-day guide
MATSEC IM Computing · Prepare for the day ahead.
Your checklist
Printed or downloaded admission statement / timetable entry
Bring the document that shows your candidate number, subject, session, date, time and venue. Do not rely on memory or on a friend's copy. If you have not received written confirmation of your session details, confirm with the provider (your school's examinations officer or MATSEC) before the exam day.
Valid photo identification
Bring the ID type your school or MATSEC has told you to present. Ask in advance which forms are accepted and whether a school-issued card is sufficient; confirm with the provider if you are unsure. Keep it in the same bag pocket every day so it is never left behind.
Candidate number and index number written down
Copy them onto paper as well as keeping them on your phone. You will write them on every answer booklet and any loose sheets. Phones may be collected or switched off during the session, so a paper copy is the reliable one.
Black or blue ballpoint pens (at least two) plus a spare
Use dark ink for handwritten answers so scans and photocopies are legible. Test each pen at home the night before. Avoid gel pens that smudge and pencils for anything other than diagrams, unless the paper's instructions say otherwise.
Pencil, eraser and sharpener
Needed for flowcharts, diagrams, tables and any rough work. Keep rough work clearly labelled and crossed out if it is not to be marked, following the instructions printed on the paper.
Clear pencil case or transparent pouch
Many centres require see-through storage so invigilators can check equipment quickly. Confirm with your centre whether a clear case is compulsory; if not stated, a clear one is never wrong.
Wristwatch (non-smart, no alarms)
Wall clocks may be behind you or hard to read. A plain analogue or digital watch without communication features is normally acceptable, but smartwatches and fitness bands are almost always prohibited, so leave them at home. Confirm with the provider if you depend on a watch for timing.
Water in a clear, label-free bottle
Check your centre's policy first; some venues allow it, others do not. If allowed, remove the label and keep the bottle on the floor, not on the desk.
Confirm the venue, room and arrival time
Do a dry run or check the route and travel time in advance. Aim to arrive well before the stated reporting time so that ID checks and seating do not eat into your reading time. If the venue is unfamiliar, confirm the exact building and entrance with your school.
Know the paper's structure and equipment rules
Re-read the specification and any advance material for the practical paper: number of questions, whether there is a choice, whether rough work counts, and whether any software or reference material is permitted. If the rules for your session are not clearly published, confirm with the provider rather than guessing.
Leave prohibited items at home
Smartphones, smartwatches, earphones, notes and any unauthorised electronic device should not enter the exam room. If your centre requires phones to be handed in, know where and when. Do not carry revision notes into the room, even in a pocket.
Plan food, medication and rest
Eat a normal breakfast, bring any prescribed medication you may need and tell the invigilator in advance if you have a medical condition. If you have approved access arrangements, confirm with the provider that the venue knows about them before the day.
Plan the day
Switch from learning new content to consolidating. Rework past-paper questions on the topics you get wrong most often, and write out from memory the structures you must produce under pressure: input-process-output breakdowns, pseudocode for standard algorithms (linear search, counting, totalling, finding max/min), truth tables, and flowchart symbols. Time at least one full paper under exam conditions so you know your pace per question.
Assemble your kit in one bag: pens, pencil, eraser, sharpener, clear case, ID, admission statement, candidate number, water bottle if permitted. Check the venue, travel route and reporting time. Resolve any uncertainty now, not on the morning: ask your examinations officer about ID, permitted equipment and access arrangements.
Do a targeted review of the highest-yield practical skills: tracing a short algorithm by hand and showing a table of variable values, converting between pseudocode and a flowchart, writing and interpreting SQL for SELECT with WHERE, ORDER BY and simple joins, normalising a small table to third normal form, and completing truth tables for AND, OR, NOT and XOR. Practise explaining each step in one short sentence, because marks are usually awarded per correct step.
Stop heavy revision in the evening. Skim your own one-page summary of formulas, definitions and command words (state, describe, explain, compare, trace, write). Lay out clothes, bag and documents by the door. Charge nothing you cannot bring, and remove smart devices from the bag. Sleep at your normal time; a rested candidate traces algorithms more accurately than a tired one.
Eat breakfast, re-check the bag against the checklist, and leave with a buffer for delays. Arrive at the reporting time, not the start time. Once seated, read the front of the paper carefully: number of questions, marks per question, whether there is a choice, and any instructions about rough work or answer format.
Read the whole paper before writing. Mark questions you can do confidently, ones needing thought, and ones to attempt last. Budget time roughly in proportion to marks, and keep a few minutes at the end for checking. Note the command word in each question so you answer at the right depth.
Show working for every calculation and every algorithm trace; method marks are usually available even when the final answer is wrong. For pseudocode, use consistent indentation and declare variables. For flowcharts, use the correct symbol shapes and label every branch. For SQL, write clauses in the standard order and check quotation marks and semicolons. If a question is worth several marks, give several distinct points rather than one long sentence.
Check that your candidate number is on every booklet and loose sheet, that all answers are numbered as on the paper, and that no answer is stranded in rough work without being clearly indicated. Re-read questions you found ambiguous and make sure you answered the question asked, not the one you expected. Hand everything in as instructed.
Rules to check
Bring the identification your centre requires and place it on the desk for checking. If you are unsure which documents are accepted, confirm with the provider before the exam day; do not assume a library card or a photograph on a phone will be accepted.
Follow the invigilator's instructions on start, stop and collection times. Writing after the instruction to stop, or before the instruction to start, is normally treated as malpractice, so put your pen down immediately when told.
Keep all unauthorised items, especially phones, smartwatches, earphones and notes, out of the exam room or handed in as directed. A device that rings or vibrates during the session can lead to disqualification even if you did not use it.
Raise your hand and wait for an invigilator if you need to leave the room, feel unwell or need more paper. Do not communicate with other candidates in any way during the session, including borrowing equipment.
Ask the invigilator only about printed instructions or missing pages, not about the subject content of a question. Invigilators cannot explain, hint at or interpret questions for you.
If you believe there is an error in the paper, state your assumption clearly next to your answer and continue. Report it to the invigilator afterwards; do not leave a question blank because you think it is misprinted.
Marks are awarded for correct method and clear communication as well as final answers, so show working, label diagrams and use the technical vocabulary of computing accurately. Legible handwriting and correct numbering protect marks you have earned.
Access arrangements, extra time and separate rooms must be approved in advance. If you think you qualify, or you are unsure whether your arrangements are in place, confirm with the provider well before the exam; they cannot usually be arranged on the day.
