ISRO Scientist Mechanical exam-day guide
ISRO Scientist Mechanical · Prepare for the day ahead.
Your checklist
Confirm the current admit card and photo-ID requirements with the provider
ISRO recruitment is run through the ISRO Centralised Recruitment Board (ICRB) and the exact ID set, photograph/signature specifications, and admit-card download window can change between cycles. Download the admit card as soon as it is released, print at least two copies, and check the name, roll number, exam centre address, reporting time, and paper code character by character. If anything is wrong, contact the provider immediately rather than correcting the printout yourself. needs_review
Original photo identification matching the admit card
Carry the original (not a photocopy or phone image) of the ID type the admit card names, plus one photocopy. Keep the same ID you used in the application; a mismatch between application details and the ID presented is a common reason for being turned away. Confirm the accepted ID list with the provider. needs_review
Printed admit card, multiple copies
One copy is typically collected or stamped at the desk, so keep a second copy with you. Do not rely on a digital copy on your phone, and do not write notes on the admit card.
Passport-size photographs
Carry several recent photographs matching the specification given in the notification (background colour, size, date). They are sometimes required for the attendance sheet or any on-the-spot form; confirm the exact number and specification with the provider. needs_review
Transparent water bottle and simple stationery
Bring a transparent bottle and, if permitted, a black or blue ballpoint pen and a simple pencil/eraser. Do not bring pencil cases, pouches, or anything with printed text into the hall. Confirm which stationery is allowed for a computer-based versus paper-based test. needs_review
Leave prohibited items at home or with a companion
Phones, smartwatches, fitness bands, Bluetooth earbuds, calculators, smart glasses, and any paper or books must not enter the hall. There is usually no secure storage at the centre, so plan for this before you travel.
Rehearse the route and reporting time
Do a dry run or map the route to the centre, including the last-mile walk. Plan to arrive well before the reporting time printed on the admit card; late entry is commonly refused and no amount of explanation reverses it. Confirm the reporting time and gate-closing rule with the provider. needs_review
Know the paper pattern before you walk in
The written test is objective, typically covering the relevant engineering discipline plus aptitude/general ability components, with a negative-marking scheme. Confirm the current pattern, duration, total marks, and negative-marking fraction from the official notification, because these vary by post and cycle. needs_review
Read the on-screen or OMR instructions carefully
For a computer-based test, spend the first two minutes on the instruction screen: how to mark, how to clear a response, how to flag for review, and how to navigate. For an OMR sheet, confirm the booklet series and roll-number bubbles before answering anything.
Plan for post-exam document retention
Keep the admit card, a copy of the application, and your ID safe after the exam. Shortlisting stages usually require them again, and the admit card is often requested at the interview or document-verification stage.
Plan the day
Switch from learning new topics to consolidation. Review your own formula sheet, sign conventions, standard values, and the topics you have repeatedly got wrong. Do one timed full-length mock under exam conditions, then spend more time analysing errors than taking the test. Stop opening new reference material.
Confirm logistics: centre location, travel, and where you will sleep. Print the admit card and ID copies, assemble the document pouch, and lay out clothes. Do a light revision of high-yield areas only, such as core mechanical fundamentals and aptitude shortcuts, and check the negative-marking rule so your guessing strategy is deliberate.
Do a short, calm review of your summary notes in the morning and stop by early evening. Eat familiar food, avoid alcohol and heavy caffeine late in the day, and sleep at your normal time. Set two alarms and a backup. Pack the pouch by the door. Do not attempt a full mock this late; it costs confidence more than it adds marks.
Eat a normal breakfast, re-check the pouch (admit card, original ID, photographs, pen), and leave with a buffer that absorbs traffic or transport failure. At the centre, follow staff instructions, complete any attendance or biometric formalities, and find your seat early. Use the waiting time for a brief glance at formulas, not for anxious discussion with other candidates.
Read the instructions, verify your name and roll number on the screen or sheet, and note the section timings and total question count. Take a few steady breaths and start with questions you can solve cleanly to build rhythm.
Work in passes: first sweep for questions you can answer quickly and accurately, second pass for ones needing calculation, and a final pass only for educated guesses where negative marking still favours you. Track time against question count, not against the clock alone. If a question resists for more than about a minute and a half, flag it and move on. Leave the last few minutes to confirm that no response is left unmarked by accident and that flagged items are resolved.
Note your rough attempt count and confidence per section while memory is fresh, in case you later need to judge whether to prepare for the next stage. Keep all documents. Wait for official answer keys and results from the provider; do not rely on third-party memory-based keys for decisions about your performance.
Rules to check
Carry the original photo ID named on the admit card; photocopies, expired documents, and images on a phone are generally not accepted. Confirm the accepted ID list with the provider before exam day. needs_review
Electronic devices of any kind are prohibited inside the test hall. Switching a phone off is not a substitute for leaving it outside; possession can lead to debarment, so treat this as a zero-tolerance rule.
Follow the reporting time exactly. Candidates arriving after the gate closes are normally not admitted, and no extra time is given for late arrival. Confirm the gate-closing rule with the provider. needs_review
Do not communicate with other candidates once inside the hall, and do not look at another candidate's screen or sheet. Invigilators can cancel your candidature for impersonation, unfair means, or disruptive behaviour.
Understand the scoring before you guess: the paper carries negative marking, so blind guessing can reduce your score. Confirm the exact penalty for the current cycle from the official notification and set a personal guessing threshold. needs_review
Breaks are generally not permitted during the test; use the washroom before entering the hall. If a medical need arises, raise your hand and follow invigilator instructions rather than leaving your seat unescorted. needs_review
Do not remove any test material, rough sheets, or stationery from the hall unless the invigilators explicitly say it may be taken. Hand in or leave everything as instructed.
All decisions on eligibility, selection, and final scores rest with the recruiting authority. Any request about re-evaluation, answer keys, or score disclosure must go through the official channel named in the notification; confirm the procedure with the provider. needs_review
