B.Arch

Most important topics to focus on while preparing for B.Arch exams. It has 2 parts.
Part 1 being Mathematics & General Aptitude
Part 2 being Drawing test.
Part 1 Consists of - MATHEMATICS
Algebra: Definitions of AP and GP; General term; Summation of first n-terms of series. Arithmetic/Geometric series, AM, GM and their relation; Infinite GP series and its sum.
Logarithms: Definition; General properties; Change of base.
Matrices: Concepts of m x n (m 3, n 3) real matrices, operations of addition, scalar multiplication and
multiplication of matrices. Transpose of a matrix. The determinant of a square matrix. Properties of determinants (statement only). Minor, cofactor and adjoint of a matrix. Nonsingular matrix. The inverse of a matrix. Finding the area of a triangle. Solutions of system of linear equations. (Not more than 3 variables).
Trigonometry: Trigonometric functions, addition and subtraction formulae, formulae involving multiple and sub-multiple angles, the general solution of trigonometric equations. Properties of triangles, inverse trigonometric functions and their properties.
Coordinate geometry
3-Dimensional Co-ordinate geometry: Direction cosines and direction ratios, distance between two points and section formula, equation of a straight line, equation of a plane, distance of a point from a plane.
Theory of Calculus
Application of Calculus
Permutation and combination
Statistics and Probability
GENERAL APTITUDE -
Objects, texture related to architecture and built environment. Interpretation of pictorial compositions, visualizing three-dimensional objects from two-dimensional drawing. Visualizing different sides of 3D objects. Analytical reasoning, mental ability (visual, numerical and verbal), general awareness of national/ international architects
Mathematical reasoning
Sets and Relations
Part 2 - DRAWING TEST
Understanding of scale and proportion of objects, geometric composition, shape, building forms and
elements, aesthetics, colour texture, harmony and contrast. Conceptualization and Visualization through structuring objects in memory. Drawing of patterns - both geometrical and abstract. Form transformations in 2D and 3D like union, subtraction, rotation, surfaces and volumes. Generating plan, elevation and 3D views of objects. Creating 2D and 3D compositions using given shape and forms. Perspective drawing, Sketching of urbanscape and landscape, common day-to-day life objects like furniture, equipment etc., from memory.

KIITEE B.Arch is an exam organized by KIIT Institute for aspirants who want to take admission in KIIT for B.Arch programme. Aspirants who want to take admission in this college have to score more than 50% marks in class 12th including physics and maths as subjects and have to score a good rank in KIITEE. This exam is just to check how much students have studied in class 12th and is he or she really eligible for this programme or not.
So the questions in B.Arch KIITEE are not so tough in comparison to NATA or JEE Mains paper 2 exam. There is no need to prepare separately for KIITEE. Just prepare for NATA or JEE Mains paper 2 with full concentration and then definitely one can score good marks in KIITEE exam. There are many coaching institutes such as BRDS, NATA Tutorial, Pahal Design for NATA exam and by joining any one of them one can prepare for any other exam as well.

There is no practical relations between B.Tech in computer Science and B.Architecture. As you know that these two have no direct relations.
However, if you are asking for difficulty level, then I would say that B.Tech CS is more difficult than B.Arch. Actually, this is my personal bias. Some students may find B.Tech CS very easy. So, the difficulty level is all a relative term. Out of the given two options, which one is better, completely depends upon you and your future goals. If you want to make career in Computer Science, Information Technology, Hacking, or any computer (or IT) related stuffs, then B.Tech CS is the best option, wheares B.Arch will leads you somewhat in civil engineering fields. This gives you the chance to become an Architect, Planner, Designer etc.
Now, the whole scenario is in front of you. Identify your interest and your dreams. And make plans according to it.

Earlier, people use to think that B.Arch and B.Planning are the same course. But, since the world of architecture is widening and diversifying, the difference between the two came into being. B.Planning is the one, where you get to plan whole city, you can also go for traditional Masters in civil engineering after that it will boost your career immensely. As it's name suggest that your profile will be limited to the Planning. After that comes the role of Architecture. In B.Arch, you will learn the execution of what the plan has been developed by the planner. The job profile is somewhat different nowadays. After doing B. Planning, your role will be to plan to take all the factors into consideration and client's demands. And, after doing B.Arch, you have to organize the plan to make it real. To summarize, B.Planning involves planning while B. Architecture involves implementation.
