How often is this unit asked?

Twelve times between 1991 and 2026, appearing in four of the last ten papers. It is smaller than most Ancient India units but overlaps heavily with the art and science questions set elsewhere.

What is the difference between Nagara and Dravida temples?

Asked directly in 2022. Nagara temples carry a curvilinear shikhara over the sanctum and usually lack enclosure walls; Dravida temples have a pyramidal vimana, enclosure walls and, later, monumental gopurams. Give a named example of each.

Why is Kalhana treated as exceptional?

The Rajatarangini uses inscriptions, earlier chronicles and critical judgement to write a continuous history of Kashmir. It is the standard reply to the charge that early India lacked historical consciousness.

Is science and technology still examinable?

Yes. It has not been asked since 2011, which in this paper usually means it is due. Prepare mathematics, astronomy and metallurgy with named figures and works.
