Of 5 pairs of identical twins & a classroom comedy of errors

A school in Mangaluru, India, has five pairs of identical twins in the same class, posing a challenge for their teacher to differentiate between them. The twins, all girls, have been studying together since grade one and will continue to do so until they complete high school. The headmistress of the school admits to mistakenly reprimanding the wrong twin for incomplete assignments. However, some classmates have found ways to identify the twins based on physical characteristics such as birthmarks and skin tone.
