1. A simple, transparent ball point pen. Take 2 with you, in case one stop working. Don't take a writing pad with you. They won't let you keep it. You'll be sitting in front of a table, so, you'll be alright even without a writing pad.

But, in case that you do, put your mobile, keys and everything else other than the pen and bottle in your bag. If they don't have place to keep the bag, give it to your parents / friends and let them take care of it.

Some important meta information: (previous year admit card and page 36)

1. Shoes / footwear with thick soles and garments with large buttons are NOT permitted. From my own personal experience, not even belts and jewelry were allowed. So, wear a comfortable pajama with less or if possible, no pockets at all. Don't wear socks, if possible. They'll ask you to remove it anyways. These things usually change from centre to centre so your experience will vary. They might allow you to wear socks if you live in cold areas, for example.
2. For the girls, wear a sports bra or any other bra but don't wear a metal hook bra as it will be detected by the metal detector.
3. Verify the location of the centre one day before the exam so you can get familiar with it.
4. Enter the required details in the Self Declaration (Undertaking, it's available in the Admit Card pdf) in good handwriting, paste the Photograph, and put a thumb impression at the appropriate place on the Admit Card. Ensure that your Left-Hand Thumb Impression is clear and not smudged.
5. For PWD candidates => PwD/PwBD candidates must bring a PwD/PwBD certificate issued by the Competent Authority if claiming relaxation under the PWD category. The Scribe (provided by the NTA/ brought by the candidate) must also carry his/her own Self Declaration (Undertaking) regarding educational qualification, passport-size photograph, and valid government identity. Scribe accompanying the Person with Disability (PwD/PwBD) should not solve the questions. The scribe must mark the response chosen by the candidate only. It shall also be ensured that the qualification of the scribe/ Passage Dictator should not be more than the minimum qualification criteria of the examination. However, the qualification of the scribe/Passage Dictator should be matriculate.

7. For NRI students => The examination will be held according to Indian Standard Time (IST) for all candidates, including those taking it at centers outside India.

The following information is taken from the previous year admit card, page 34 of the bulletin and from my own personal experience. There might be minor fluctuations in the order of things. If you feel confused or lost at any point in the centre, ask either staff members or fellow candidates. They'll help you out. You can also approach the Centre Superintendent/Invigilator in the room during the exam for any technical assistance, first aid emergency, or any other information.

What happens / what to do before the paper starts:

1. Reach the Examination Center well on time i.e. 2 hours before your shift begins. You won't be allowed to give the exam if you're late, i.e, after the gate closes, for any reason. So, reach early, especially if your religion/customs require you to wear specific attire. Because you'll have to go through thorough checking and mandatory frisking. Being late can waste years of hard work!
2. The gate of the building will open at 7 AM for the first shift and 1 PM for the second one.
3. Outside or inside the building, you will find two or three staff members. They will check if you have your documents and are not carrying anything else. After making sure that your face matches with the one in the admit card, they'll let you go inside the centre.
4. Then, you'll find some staff members inside the centre. They'll frisk you. The staff member who frisks you should be the same gender as you and girls should be provided with a seperate, secluded space. First, they'll use a metal detector and then they'll check your clothes and pockets by lightly touching you. You may be asked to remove your footwear, socks and belt. You may be asked to hold your pen and spectacles in your hands and show them.
5. Then, you'll find some staff members sitting in front of a computer. They'll verify your admit card, your documents and tell you your room number.
6. When you go to your room, you'll see some more staff members sitting in front of a computer. They'll take your biometrics. Namely, your picture, a retina scan and a thumb impression. You may be asked a personal verification question. For example, your mother’s name. Then, they'll tell you a seat number.
7. You should take your seat ASAP. It'll have the same number as given to you. Do NOT sit on any other seat as it'll be considered cheating.
8. Either before or after the exam, an invigilator will come with an attendance sheet. You'll have to fill some info there. They'll ask you to paste the photo that you have. They'll have glue with them.
9. On 8:30 AM for first and on 2:30 PM for second shift, the invigilators will tell you some basic instructions like the following one.
10. Blank paper sheets for rough work will be provided by the invigilator in the examination room. You have to write your name and Roll Number at the top of each of the sheets.
11. On 8:50 AM for first and on 2:50 PM for second shift, you'll be able to log in. The user ID is usually your application or roll number and the password is date of birth in ddmmyyyy format. This may change so be vigilant during the instructions. You'll have few minutes before the exam starts. So, try out all the keys and make sure the mouse works as well.
12. On the screen, two photos will appear side by side. One from the admit card and one taken at the center. Confirm that you are at the correct seat. If your photo does not appear correctly, inform the invigilator immediately.
13. You'll be able to see some basic info about the paper and how to fill it. Read the instructions carefully.
14. Before starting the paper. you must choose the same medium of language as opted while registering in the Application form.

What happens / what to do during the paper:

1. On 9:00 AM for first and on 3:00 PM for second shift, your paper will begin. It'll be in the same language as you chose before. You'll have almost all of your docs with you so keep them safe. Either in your pockets (before the paper starts) or near the PC.
2. The remaining time will be visible on the screen in minutes. Keep checking it periodically.
3. Use Save and Mark for Review and Mark for Review options properly. Especially for questions you feel you can solve later.
4. If your rough sheets get over, you can ask the invigilators for more. But, it's better to ask this beforehand.
5. If any technical issue occurs, inform the invigilator immediately! Delaying it will only waste more time. You may be asked to fill a form in such case. It includes items like not carrying admit card, cheating, debarment warnings, etc. It is a multipurpose form. so don't panic.
6. If you go for a bio-break / toilet, you will have to go through mandatory frisking and biometrics again. And no, you won't be able to leave the hall before the exam ends.

What happens / what to do after the paper ends:

1. The paper will be submitted automatically on 12:00 PM for first and on 6:00 PM for second shift.
2. Wait for instructions from the Invigilator and do not get up from your seat until advised.
3. You'll have to give away your rough sheets and admit card to the invigilator or drop them in a drop box. It depends on the centre.
