NATA

Hi,
I'll give you the difference between NATA and JEE: Both the exams share the similarity that is they both are conducted for the admissions to the 5 Year Bachelor of Architecture Course in the various colleges of India but the fact that makes them apart (dissimilarity, can also be termed as difference) is JEE Main Paper 2 is conducted for the admission to the NITs and centrally funded colleges Across the nation and the NATA Exam is conducted for the admissions to the B.Arch colleges in India except NITs and centrally funded colleges. NATA is compulsory Exam conducted by the Council of Architecture and most of the institutes /colleges accept only NATA scores. So, if you plan to stay in Gujarat for your Bachelors then give NATA as there aren't any NITs, IITs or SPA for architecture in Gujarat.
You should rather look at these colleges:
CEPT University, Ahmedabad
Nirma University, Ahmedabad
Indus University, Ahmedabad
Indubhai Parekh School of Architecture, Rajkot
Sarvajanik College of Engineering and Technology
School of Architecture, Vadodara Design Academy
Navrachana University, School of Environmental Design and Architecture
Faculty of Technology and Engineering, The Maharaja Sayajirao University of Baroda
All these colleges accept NATA.

Study Plan for the National Aptitude Test in Architecture (NATA)
The basic quality students must have is an interest towards the subject of architecture. They must have an imaginative mind and the passion for drawing.
Sometimes the students might also be asked questions on architectural awareness. There is also a possibility that they might be asked to identify national and international buildings of prominence. As to answer all these types of questions correctly, students need to have a very good idea on all subjects pertaining to architecture.
Students can read newspapers and journals that have good articles on buildings and their structures. They can also refer the internet for more details.
Apart from this, they can prepare for the written examination by reading reference books and practice on old question papers.
This will give students an idea of how the exam is and will give them more confidence to attend the exam without much fear.
