TANCET exam is being conducted by Anna University on February 29 on behalf of Government of Tamil Nadu. The exam is mainly for admission in Tamil Nadu colleges, hence the exam centres which are alloted are situated only in the state. Henceforth, candidates were not given any option to select Hyderabad as an exam centre.
No, all the exam centers are situated in Tamilnadu no other centre is outside Tamilnadu so you need to opt among the following cities in Tamilnadu
Other states candidates can also apply for Tancet exam. No, you can't write tancet exam from hyderabad because there is no exam center for it. If you want to give exam, you need to come in Tamilnadu.
