Above topics are grouped
together since they deal with the portion of QA that can be visualized. Of the
three, maximum weightage is given to geometry, although every CAT
paper will have 3-4 questions on mensuration, as well as a couple of
questions on coordinate geometry, totaling about 25-30% of questions in the QA
section.
Topics that need to be covered in geometry are basic theorems
involving triangles, circles and parallel lines. A common type of question that
is often asked in CAT is to find the value of certain angles or length of
certain sides. Therefore, make sure that you cover topics such as congruency
and similarity of triangles.
The only things that you need to do in coordinate geometry are
straight lines and circles. Given the equation of a circle, you should be able
to comment on the centre and radius of the circle and draw it on a piece of
graph paper, and nothing more.
Similarly, you should know what the slope and y-intercept of a
given straight line equation is, and be able to draw the line on a piece of
graph paper.
For mensuration, flip through a school level textbook for
basic formulae on areas, surface areas and volumes of triangles, circles,
cylinders, cones, cuboids and spheres. Mensuration problems
are calculation intensive, and require lots of practice.
Hopefully Mock Tests
will give you required practice so that
you can achieve confidence to be successful in CAT 2012.
