Part-66 Module 5 exam-day guide
Part-66 Module 5 · Prepare for the day ahead.
Your checklist
Valid photo ID
Bring the original government-issued photo ID you used to book (passport or national identity card). Photocopies and expired documents are normally refused - confirm the exact accepted ID types with your examination provider before the day, as rules differ between centres.
Booking confirmation and candidate number
Print or download the appointment confirmation showing your candidate/licence number, module number (Module 5), date, time and venue address. Some centres ask for it at reception; confirm with the provider whether a printed copy is required.
Approved calculator
Number-system and logic-arithmetic questions are quicker with a calculator, but many centres restrict the type (non-programmable, non-alphanumeric memory, no case lid notes). Confirm the permitted calculator policy with the provider and check the battery beforehand.
Writing materials
Bring two pens, two pencils, an eraser and a small ruler in a clear pouch. Confirm with the provider whether rough paper and pencils are supplied at the desk, since some centres prohibit bringing your own.
Confirm the exam format and pass mark
Ask your provider in advance how many questions Module 5 contains, the time allowed, whether it is paper or computer-based, and the pass mark that applies to your licence category. Do not rely on figures quoted by other candidates - the format depends on the approved organisation and the mapping to the current syllabus.
Confirm what reference material, if any, is allowed
Assume closed-book unless your provider states otherwise in writing. If any tables or formula sheets are permitted, they will normally be issued at the desk rather than brought by you.
Know the venue and arrival time
Plan the route and arrive at least 20–30 minutes before the scheduled start. Late arrival can mean refusal of entry - confirm the centre's cut-off time with the provider.
Personal items plan
Leave smartwatches, phones and notes at home or plan for secure storage. Most centres require devices to be switched off and stored away from the desk; confirm the storage arrangements in advance.
Access or special arrangements
If you need extra time, a separate room, or other reasonable adjustments, these must normally be requested and approved well before the exam date. Contact the provider as early as possible - arrangements agreed on the day are unlikely to be honoured.
Revise the Module 5 topic map, not just question drills
Cover number systems and arithmetic (binary, octal, hexadecimal, signed representations), data conversion, logic gates and Boolean simplification, computer architecture and memory, microprocessors, integrated circuits, data buses, multiplexing, fibre optics, electronic displays (CRT, LCD, LED), electrostatic sensitive devices and handling precautions, software management and configuration control, EMI/EMC, and typical aircraft digital/electronic systems.
Practise the calculation types by hand
Work through binary/decimal/hex conversions, two's complement, simple gate truth tables and basic bus/word-length reasoning using only the calculator you will actually take in. Timed practice under exam conditions is more useful than reading notes in the final day.
Rest and health basics
Sleep properly the night before, eat beforehand, and avoid alcohol in the preceding 24 hours. Bring water if the centre permits it - confirm the drinks policy at the desk.
Plan the day
Re-read the syllabus content list for Module 5 and tick off any topic you cannot explain aloud. Spend the remaining time on weak areas rather than re-reading material you already know.
Contact the provider to confirm venue, start time, ID requirements, calculator and reference-material policy, and any access arrangements. Get anything important in writing if you can.
Do one or two full timed practice sets at the same time of day as your real exam, then review errors by topic, not just by answer.
Do a light review of formula-type content (number bases, gate symbols, bus and fibre terminology, ESD precautions) and then stop. No new material, no cramming past midnight.
Pack your bag: ID, confirmation, approved calculator, pens/pencils/eraser, water if allowed. Lay out clothes and check your travel route and journey time, including any buffer for delays.
Set an alarm with a backup, confirm the alarm is actually on, and go to bed at a reasonable hour.
Eat a proper meal, avoid last-minute cramming of unrelated topics, and arrive at the centre early with your ID and confirmation ready at hand.
Follow the invigilator's instructions for sign-in, ID check, and storing personal belongings. Ask for clarification if you do not understand a conduct rule - better to ask before the paper starts.
Read the instructions and check the question count and time allowed. Answer the questions you are confident about first; flag anything needing calculation or a second read.
Return to flagged items, show your working for conversions and truth tables, and watch for unit and base-subscript traps. Only change an answer if you find a concrete reason.
Check that no question is left blank (unless the provider applies a penalty for wrong answers - confirm this in advance), check your candidate details on the answer sheet or screen, and submit as instructed.
Rules to check
Bring original photo ID matching your booking. Candidates without acceptable ID are normally refused entry, and the accepted document types are set by the provider - confirm them in advance.
Follow the invigilator's instructions at all times. Mobile phones, smartwatches and any unauthorised notes or devices must be switched off and stored as directed; possession at the desk can lead to invalidation.
Do not communicate with other candidates once the examination has started, and do not attempt to copy, photograph or remove any part of the paper. Suspected malpractice is handled under the provider's procedure and can affect your whole licence application.
If you need to leave the room, raise your hand and wait to be escorted. Toilet breaks during the exam are at the invigilator's discretion and the clock normally keeps running - confirm the centre's breaks policy with the provider.
If you feel unwell or there is a disturbance, tell the invigilator immediately rather than continuing silently; special consideration is usually time-limited and needs to be recorded at the time.
Ask the invigilator if a question appears misprinted or the software misbehaves. They cannot explain technical content, but they can log an issue that may support special consideration.
Scoring is set by the approved organisation: Module 5 is normally assessed as a multiple-choice paper with a pass mark determined by the applicable Part-66/Part-147 requirements for your licence category. Confirm the exact number of questions, pass mark and any per-topic requirement with your provider rather than assuming.
Results issue and appeal routes vary by provider. Confirm how and when results are released, and what the re-sit and appeals process is, before you sit the exam.
