There are conditions applied with respect to Tattoos. Permanent body tattoos are permitted only on the inner face of forearms i.e. from inside of the elbow to the wrist of both the hands and reverse side of the palm/back (dorsal) side of both hands. Though, there are no restrictions on the size or type of tattoo that have been specified. However, it is advised to not have a tattoo till you clear the exam, unless you are from a tribe or follow a custom that mandatorily required you to have a tattoo.
