IIT

IIT Madras creates a special academic committee. After the initial IIT JAM 2024 answer keys are published, candidates will have the opportunity to raise objections. The committee of experts will study any objections, and will announce results once an objection is made within the timeframe allowed. Candidates can also submit files as proof when submitting their objection.

There have some serious consequences when bringing prohibited items to take any IIT JAM exams: 

Disqualification from the Exam: You can be disqualified from the exam, meaning your test could be taken away from you, and you could leave the examination room with the exam immediately invalidated. 
Seizure of Items: Any prohibited item found on your person will be taken from you by the exam officials. 
Possibly Criminal Action: Depending upon the item and the terms of the examination centre, in some cases bringing a prohibited item may incur some form of charges.

In general, no, you should not wear jewellery to the IIT JAM exam centre.

Security Checks: You are likely to have to go through security checks by way of metal detectors at the entrance. Jewellery can trigger metal detectors and causes delays, and can only be annoying at the examination.

Some institutions may have specific guidelines (e.g., wear shirts or t-shirts, jeans or trousers, and recommend against women wearing high heels.)
