Iran Nezam Mechanical Design Exam exam-day guide
Iran Nezam Mechanical Design Exam · Prepare for the day ahead.
Your checklist
Printed admission card / registration confirmation
Print the confirmation issued by the organizing body (typically the relevant engineering organization or university admissions office). Verify your name spelling, national ID number, exam field code, and test center address match your ID exactly. If the card has not arrived in time, confirm the procedure with the provider rather than assuming you can enter without it.
Original national ID card (kart-e melli) or valid passport
Bring the original document, not a copy or photo. Check the expiry date now; an expired ID may be refused. If your ID is lost or expired, ask the provider in advance what substitute document they accept - do not rely on a driver's license unless confirmed.
Two or more black or dark-blue ballpoint pens
Mechanical design papers are largely calculation-based, so bring pens you have already written with. Test each one the night before. Avoid gel pens that smudge under a ruler and pencils unless the provider explicitly permits them for answer sheets.
Non-programmable scientific calculator
Choose a basic scientific model with no graphing, no text storage, and no communication capability. Programmable or graphing calculators are commonly prohibited; confirm the permitted list with the provider. Bring spare batteries or a second identical unit.
Mechanical pencils, spare leads, eraser, sharpener
Useful for scratch work and sketching free-body diagrams or tolerance stacks. Keep them in a clear pouch so invigilators can inspect quickly.
Ruler, set square, protractor, and compass
Drawing instruments are frequently needed for geometry, linkage layout, and section sketches. A 30 cm transparent ruler and a 45/60 degree set square cover most needs.
Printed formula and unit-conversion sheet you prepared yourself
Only if the provider allows personal reference material - many exams supply their own tables or forbid outside notes. Confirm the policy in writing. If notes are allowed, keep them on plain paper with no worked solutions.
Watch (non-smart) and clear water bottle
Wall clocks may be poorly placed. A plain analog or digital watch without connectivity is usually acceptable; smartwatches are almost always banned. Bring water in a transparent bottle with the label removed.
Review the official syllabus and scoring weights
Confirm which topics carry the most marks (commonly machine design, stress analysis, materials, and manufacturing considerations) and how negative marking, if any, is applied. Ask the provider for the current weighting rather than relying on older forum posts.
Plan and rehearse the route to the test center
Check the exact building and gate, estimate travel time with morning traffic, and identify a backup route. Arrive well before the stated reporting time; late entry rules vary and should be confirmed with the provider.
Sleep, meal, and medication plan for exam day
Protect 7–8 hours of sleep for the two nights before. Plan a light, familiar breakfast and bring a small snack if breaks are permitted. Carry any prescription medicine and inform the invigilator if you may need it during the test.
Leave valuables and electronics at home
Phones, smartwatches, earbuds, and bags are usually collected or prohibited at the desk. Carry only what the checklist requires plus your ID and admission card.
Plan the day
Stop learning new topics. Re-read your own summary sheets for machine elements, failure theories, fatigue, bearings, gears, tolerances, and material selection. Do one timed mini-paper under exam conditions to calibrate pacing, then mark it and list only the three weakest areas to revisit.
Assemble the physical kit: ID, admission card, pens, calculator with fresh batteries, drawing instruments, watch, water bottle. Put everything in one bag and leave it packed. Confirm the test center address and reporting time from the official notice.
Do a second timed session focused on calculation speed: unit conversions, stress and deflection formulas, bearing life, gear ratios, and tolerance stack-ups. Practice writing clean intermediate steps so partial credit is visible if your final number is wrong.
Light review only: formula sheet, common unit traps (N vs kN, MPa vs Pa, mm vs m), and sign conventions. Prepare clothes and ID by the door. Eat a normal dinner, avoid heavy caffeine after midday, and go to bed at your usual time.
Eat a normal breakfast, re-check that the ID and admission card are in the bag, and leave with a buffer of at least 30–45 minutes. Do not study new material in the car or lobby; skim only your one-page formula summary.
Use the restroom, silence and stow your phone as instructed, and locate your seat and the clock. Listen carefully to invigilator instructions about filling the answer sheet, coding the booklet, and permitted materials.
Read the instructions and scan the whole paper. Note the mark allocation per question and identify which sections you will attempt first. Write your name and ID exactly as instructed before starting.
Work in passes: first answer questions you can solve confidently, then return to harder ones. Budget roughly one minute per mark as a starting estimate and adjust to the actual paper. Show assumptions, units, and free-body diagrams - they often earn partial credit. If a calculation stalls for more than a few minutes, mark it and move on.
Check that every intended answer is transferred to the answer sheet, that question numbers align, and that units and significant figures are stated. Verify your ID coding and signature. Do not erase answers in a rush unless you are certain of the correction.
Rules to check
Bring the original identification document named in the official notice; copies, photos, and expired documents are commonly refused. If your situation is unusual, confirm acceptable alternatives with the provider before exam day.
Electronic devices - phones, smartwatches, earbuds, and programmable or graphing calculators - are generally prohibited at the desk. Confirm the permitted calculator list with the provider and keep devices switched off and stowed as instructed.
Enter only with the materials the provider allows. Personal formula sheets, textbooks, and annotated notes are often banned; if reference tables are supplied, use only those.
Follow invigilator instructions on timing, answer-sheet coding, and leaving the hall. Do not start before the signal or continue writing after the stop signal; doing so can lead to disqualification.
Breaks and restroom visits are usually limited and may be escorted. Ask the invigilator before leaving your seat, and expect that no extra time is granted for breaks.
Any communication with other candidates, looking at another answer sheet, or sharing materials is treated as misconduct. Keep your work covered and your eyes on your own paper.
Scoring rules - including whether wrong multiple-choice answers carry negative marks and how partial credit is awarded for calculations - differ between administrations. Read the instructions on the paper and confirm the current policy with the provider.
If you believe there is an error in a question or a disturbance in the hall, raise it calmly with the invigilator at the time and note it afterward; do not attempt to resolve it by changing your answer sheet.
