The first factor you must work on for solving reasoning question is, developing a warning system about the difficulty level of a question.
One of the greatest quandaries of a student taking the CAT is the amount of time spent per question in the reasoning section, which is notoriously time consuming.
One extremely crucial aspect of solving reasoning questions is the degree of control you have while cracking one of them. Indeed, this is an important factor even during the decision making process for data interpretation questions.
Observations have shown that most test takers realize too late into solving a question, that they may not be able to solve it, and when they do realize that a question set was not worth investing time in, they have already invested too much time in a futile attempt to crack it.
What you need to know at the outset is, that based on the level of your abilities, various question sets in DI and reasoning may be within, or outside your grasp. Hence, the ability to pinpoint whether you would be able to solve a question set, when going through it for the first time, could be a big differentiator and go a long way towards improving your test scores.
There are a few concrete steps you could take in order to develop this ability for DI and reasoning question sets. However, as we are focusing on the reasoning section toady, the first factor you must work on for solving reasoning questions is, developing an advanced warning system about the difficulty level of a question.
The problem most students face when classifying reasoning questions, is that since they are all language intensive, they all tend to look the same. This is why test takers find it hard to determine whether a question set is to be solved or not.
1) You should have to use all the information available in most reasoning questions. This assumption normally holds true because redundant data questions are very rarely found.
2) The other thing you need to consider is the number of variables involved. Typically, the more variables provided, the more difficult the question is likely to be.
3) Given this, your approach to every reasoning question should be based on a sentence by sentence analysis of the question. Look at the clues closely, and for each statement, evaluate whether it is a direct or an indirect clue. Direct clues give you direct relationships between the variables involved, and hence are easy to place (eg: Amit is wearing the red shirt) Indirect clues, on the other hand, are far more difficult to place, and have to be used at specific points in the solving of a problem. (e.g. The person wearing the blue shirt lives somewhere to the right of the person who hates coffee and he is not Amar). Naturally the higher the proportion of direct clues, the easier the question would be. On the other hand, if the indirect clues are higher, the question starts becoming more and more difficult to solve, and this single fact, can go a long way in helping you distinguish the tough reasoning question from the easy one.
To be thorough in all sections of cracking CAT student aspirants must at least undergo a one year coaching from expert coaches and practice previous 5 to 6 years papers under his guidance. The aspirants are benefited in 2 ways, develop their speed and understand the solving approach of each question.
