## How to prepare for CAT – I

We are slowly getting closer to the business end of the CAT 2018 season. Some of you would have joined for classroom programs as early as last June, a lot of you in Jan and I am sure a few are yet to start but all of you know that you have to start your prep with all seriousness. All of you know that it is time to do more than just attend classes, meet your CAT prep mates and go back home. So it is not a surprise that I am getting a lot of queries – how many hours of prep should I be putting in daily to crack CAT 2018? – what should I be doing on a daily basis to crack CAT 2018? – how should I plan my prep for CAT 2018? This post is going to be dedicated to all things related to a prep plan for CAT 2018.

## CAT Quantitative: How to approach a problem

One of the things that weighs constantly on CAT test-takers is how they can increase their speed and accuracy. More often than not test-takers discover the right way to solve a problem mid-way through the problem – after they have spent about 2 minutes following one approach. So what is the best way to increase speed and accuracy? Identify the right way to approach a problem before you start solving it. Let us examine how to do this by taking an old SimCAT problem.   Given that f(x) = sec x – tan x. If f(x) = k, then what is the value of cosec x? 1-k/1+k 1+k2/1-k2 1-k2/1+k2 k2/1+k2   Rule # 1: Do not leave this problem thinking — “It is Functions + Trigonometry!“ As we discussed in a previous post, CAT problems are deliberately designed to be seemingly tough or unapproachable! This problem has nothing to do with functions, it is just a fancy way of saying if sec x – tan x = k then cosec x = ? Rule # …

## CAT Quantitative – Identifying the topic of the question

One of the reasons why the CAT seems tough to test-takers is that the questions are deceptively framed. Test-takers tend to expect questions to be neatly classified — areas, topics, concepts — so that the moment they see the problem they know what to do. But the objective of the test is to not to make things so obvious, not to make a question a matter of plugging numbers into to formulas. There are many questions that on the face of it seem to belong to one area but on closer inspection reveal their origins to be in a different area.
