Architecture

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.

Hi,
Like any other job depends on its industry, so is the condition with shipbuilding/shipping/offshore industry.
Naval Architects may work at shipyards or, alternatively, may be employed by shipping companies, classification societies, consultancies, or research institutes. Naval Architects also work in offshore companies or firms that manufacture maritime equipment, e.g. life-saving appliances or ship engines.
Like any other field, CTC varies with the location and the kind of job. In India the range varies from 25000 - 50000 INR per month. As compared to other countries India does not offer promising industry for naval architects. Even not a lot of colleges offer this course which makes the scope very now in India. In abroad depending on your field, it varies from 12 - 40 lakh INR per annum. Offshore field normally comes up with a hefty packages compared to the shipbuilding. But, nowadays due to oil price slide, there are very few offers in offshore field for freshers.
Colleges that you can look at:
US: University of Michigan, Texas A&M and University of New Orleans.
India: IIT Kharagpur and Madras, Cochin University, Indian Maritime University
Singapore: National University of Singapore, Newcastle University, Nanyang Technical University
U.K: Newcastle University, University College of London, University of Strathclyde, University of Glasgow
Other universities in Europe:
Norwegian University of Science and Technology,KTH Royal Institute of Technology,Chalmers University,
University of Nantes,
Denmark Technical University,
Rostock University.

Hi,
Go for JEE Mains paper 2 for getting admission in the best college which is School of Planning and Architecture (SPA). Others would be NITs and IITS.
The exam shall have 3 sections: Aptitude, maths and drawing (Memory, 2D Design).
Go for NCERT books first for your preparation.
Few useful reference books besides the CBSE NCERTs are:
1. A Complete Self Study Guide for B.Arch 2015 Entrance Examination (English) by P.K Mishra, Arihant Publications
2. Verbal & Non Verbal Reasoning Book by R.S. Aggarwal
3. Architecture Entrance Book by P.K. Mishra
4. Skills in Mathematics Algebra for JEE Main and Advanced by S K Goyal
Also, give National Aptitude Test in Architecture (NATA) which is also an entrance exam for institutes other that NIT and centrally state funded Institutes. This will keep your options open for all universities.
