Three steps to cracking the CAT Section 1 - Quant & DI : Part 1

So, without further ado, let us begin on this journey to scoring better in section 1.

Step 1 – Knowledge
The first thing that you need to know as an aspirant to score more in section 1 is the structure of section 1. It consists of four broad areas:

a. Quantitative Aptitude
b. Data Interpretation

There are 30 questions in section 1 which are further divided into the above four categories as:
20 or 21 questions are asked on Quantitative Aptitude. These are further divided into five sub categories:

1. Number System
2. Arithmetic
3. Algebra
4. Geometry
5. Modern Math

A very common misconception that students have is that CAT focuses a lot on Number System but that is not the case. As a matter of fact, if you consider the past 2-3 years (which is hard because papers are not available) or CAT papers from 2004 to 2008 (for which the papers are available) Number System is the least important section. Not only that, more often than not – questions which are asked on Number System are harder than the questions from other sub categories. On the other hand, the CAT paper is heavily inclined in favour of sub categories like Geometry and Algebra.

In Algebra, Functions form a major part of the questions. I would specially like to point out that complicated questions on ‘Remainders’ (questions which cannot be solved by basic rules and concepts of cyclicity), advanced questions on ‘Permutations & Combinations’ (questions which require usage of anything other than nCr), and questions on ‘Probability’ are almost never asked. But still a lot of students waste a huge amount of time preparing for these chapters. If you are among one of those students, I hope that after reading this post you would change your ways and utilize your time wisely.

9 / 10 questions are asked on Data Interpretation and these are also divided into 3 sets of 3, 3, and 3 / 4 questions each. More often than not two of these sets are easier than the third one. One of these sets is often calculation heavy whereas the other rely more on understanding the data given. More often than not questions in this part of the paper include tables with large amount of data. There is a reasonable chance of data being given in the form of bar charts or line diagrams. Pie charts are slightly less popular. Having said that, you should expect at least one set which would have data in a not traditional format like a spider web data representation or data given to you as a part of a triangle. Some students get shocked and surprised by this new form of data representation but from what I have seen in the past – these are the easiest questions to solve. Because in these, the key lies in understanding the data representation and once you do that – the questions are a cake walk. So, if you are lucky, you will get a set in non-traditional data representation format and that should be the first set that you should attempt.

I hope that if you have reached this point in the post, you are now well versed with what gets asked in Section 1. If you thought that this post was helpful, show us some love by liking / sharing / tweeting it. If not, you can always use the comment section to suggest improvements.
