No — smartwatches, fitness bands and any electronic device are banned inside the exam hall.
Only a simple analogue watch is usually allowed, and even that is restricted in some computer-based exams.
Carrying a banned device can get your paper cancelled on the spot, even if you never used it.
Leave your smartwatch at home or deposit it outside as per the centre’s arrangement.
Always read the banned-items list printed on your admit card before exam day.
