ISRO Scientist Civil exam-day guide
ISRO Scientist Civil · Prepare for the day ahead.
Your checklist
Print or download your ISRO admit card
ISRO releases the admit card on its recruitment portal before the written test. Download it as soon as it is available, check that your name, roll number, exam centre, and photograph are correct, and carry a printed copy. Confirm with the provider whether a digital copy is accepted at your centre.
Carry valid original photo ID
Bring the same photo ID whose number you entered in the application (commonly Aadhaar, passport, driving licence, PAN, or voter ID). Carry the original, not a photocopy. Confirm with the provider which ID types are accepted and whether a photocopy must also be submitted.
Bring passport-size photographs
Carry two or three recent photographs matching the one on your application, in case the invigilator asks for pasting or verification. Confirm with the provider the exact number and specification required.
Know the reporting time and gate-closing time
The admit card states the reporting time and the time after which entry is refused. Plan to reach the centre well before the reporting time, since verification queues can be long. Do not assume you will be admitted after gate closure.
Reconnoitre the exam centre in advance
Check the exact address and travel route the day before, including local transport availability and any construction or diversion. Aim to arrive with a comfortable buffer rather than cutting it close.
Carry a simple black or blue ballpoint pen
Objective tests commonly require darkening ovals on an OMR sheet. Bring two pens of the permitted colour. Confirm with the provider whether pens are supplied at the centre and whether any specific type is mandated.
Leave prohibited items at home
Mobile phones, smart watches, Bluetooth devices, calculators, and study material are normally banned inside the hall. Many centres provide no secure storage, so arrange to leave such items with a companion or at your accommodation.
Dress simply and avoid metal-heavy accessories
Security screening may involve metal detectors. Avoid belts with large buckles, heavy jewellery, and shoes that trigger repeated checks, so you are not delayed at the gate.
Read the instructions on the question booklet and OMR sheet
Fill in roll number, booklet series, and other fields exactly as instructed before starting. A mismatch between the booklet series and the OMR sheet can invalidate your answers.
Plan hydration, food, and medication
Eat a normal meal before reporting and carry water if permitted. If you need regular medication, confirm with the provider in advance how to carry it into the hall.
Check the paper pattern for your post
Confirm the number of questions, total marks, duration, and whether there is negative marking for the specific ISRO post you applied for, since these details vary by advertisement. Verify on the official ISRO recruitment portal or with the provider.
Keep the admit card after the exam
Retain the admit card and any acknowledgement until the recruitment process concludes, as these are often required at later stages such as interview or document verification.
Plan the day
Recheck the official portal for any change in exam date, centre, or reporting time, and reprint the admit card if anything changed. Confirm your travel and accommodation. Switch from learning new topics to revising formula sheets, standard derivations, and your own error log. Take one full-length timed mock in exam conditions, then spend more time analysing mistakes than attempting fresh questions.
Do a light revision of high-yield areas such as structural analysis basics, concrete and steel design principles, fluid mechanics fundamentals, soil classification, surveying computations, and environmental engineering units. Prepare your documents folder with admit card, ID, and photographs, and lay out the clothes and pen you will carry.
Visit or map the route to the centre and note the travel time plus a buffer. Pack your bag with admit card, original ID, photographs, pens, and water if allowed. Set two alarms. Stop heavy study by evening, sleep at your normal time, and avoid last-minute cramming that disrupts rest.
Eat a proper breakfast, re-verify that the admit card and ID are in the bag, and leave earlier than the mapped travel time suggests. Reach the centre before the reporting time, complete verification calmly, and locate your seat and the washroom before the hall is sealed.
Read the instructions on the booklet and OMR sheet, fill in all identification fields carefully, and check that the booklet series matches what you mark. Scan the paper briefly to judge difficulty distribution before committing to an order of attempt.
Attempt in passes: first the questions you can solve quickly and confidently, then the moderate ones, and only then the lengthy or uncertain ones. Watch the clock at fixed checkpoints rather than continuously. Reserve the final minutes for transferring or verifying OMR entries, since an unmarked correct answer earns nothing.
Hand over the booklet and OMR sheet as instructed, keep your admit card and any acknowledgement, and note down remembered questions and doubtful answers while fresh. These notes help if a answer key challenge window is later announced.
Rules to check
Carry only the admit card, original photo ID, permitted photographs, and writing instruments into the hall. Everything else, including phones and smart watches, must stay outside; confirm with the provider whether any storage facility exists at the centre.
Reach the centre by the reporting time printed on the admit card. Entry is normally refused after gate closure, and no extra time is given for late arrival, so treat the reporting time as a hard deadline.
Follow every instruction given by the invigilator and on the booklet. Do not open the question booklet before the start signal, and stop writing immediately when the end is announced.
Mark answers only on the OMR sheet in the prescribed manner. Answers marked in the question booklet or with unclear, multiple, or improperly erased marks may not be evaluated.
Verify negative marking and sectional requirements for your specific post on the official advertisement before the exam. Do not rely on memory or on what other candidates say, since rules differ across ISRO recruitment advertisements.
Any form of unfair means, including communication with other candidates, carrying prohibited material, or impersonation, can lead to disqualification and possible debarment. Confirm the exact penalty provisions with the provider.
Breaks are generally not permitted during the test. Use the washroom before entering the hall, and raise your hand if a genuine emergency arises rather than leaving your seat unannounced.
Scoring, normalization if any, and shortlisting criteria are set by the recruiting body. Read the official advertisement and any subsequent notices rather than assuming a fixed cutoff or qualifying mark.
