Quantitative Aptitude will play a significant role in CAT 2011. Familiarity with Mathematics will be crucial in deciding your selection. The level of Mathematics will be that of Standard X and logic similar to National Talent Search Examination. Pay attention to geometry, number system, algebra and questions related to speed and distance. There are different angles to each problem and it is important to understand the question before answering it.
Quantitative Ability
It is not possible to precisely tell the nature of questions but an analysis of previous papers reflects that questions are usually based on the following topics: number system, arithmetic, algebra and geometry, time-speed-distance, work and time. Furthermore, ratio and proportion, profit and loss, average, percentage, partnership, mensuration, simple and compound interest, set theory, venn diagrams, permutations and combinations are also important topics.
Important chapters
The CAT questions are not direct. They are designed to trick you in a way that is confusing. That said, these are the important chapters that should be paid attention to while preparing for QA section of CAT:
Number system
About 30 per cent questions are based on this topic in this section of CAT. 8 of the 20 probable questions can be expected this year from the number system. Application of logic will decide your success.
Geometry
It is important to understand the theorem that will be applied for solving the question. 3-4 questions are expected from geometry in CAT 2011.
Algebra
Pay attention to the basics for this topic. Log, arithmetic progression, geometric progression are important. A lot of practice and ability to deal with numbers is desired.
Arithmetic
Do not be scared of calculations. Practice previous question papers.
How to prepare
Practice mock papers and seriously solve and analyse real CAT question papers of the previous years. It is worthwhile to understand the pattern of questions. The more the practice, the better the chances of succeeding in this section. Also try to master the art of solving questions in computer based format.
80 per cent questions do not require any formula
Most questions in CAT are not formula based and have a story format. It is required that you create an image of the data in your mind and relate everything before actually solving the question.
Tips
- Try to first understand the basic level of Mathematics.
- Develop the ability to evaluate several combinations in less time.
- Read the questions carefully as they are tricky.
- Use diagrams to solve tricky questions.
