NATA

Hi Manivannan,
NATA is a compulsory Exam conducted by the Council of Architecture and most of the institutes /colleges accept only NATA scores. NATA is a test which only tests drawing and 3D interpretation skills and even students from humanities or commerce background can answer the exam.The exam does not test mathematics or science knowledge. The exam is conducted by the Architecture's Association and it helps you secure admission recognized by them and you need to apply to different institutes independently with the NATA scores. CEPT in Ahmadabad is one of the good college which accepts NATA scores.
