Divisibility Rules for CAT Quantitative Aptitude Preparation

March 30th, 2020 by

The concept of ‘divide and conquer’, derived from the Latin phrase ‘Divide et impera’, was put into use effectively by everyone from Caesar to Napoleon to The British in India. Even Gaddafi tried using the same but as current events show us – he wasn’t very effective. Dividing rather divisibility rules to be specific can come in really handy at times in solving problems based on Number Systems. The standard rules which nearly all of us are very comfortable with are the ones for 2n and 5n. For these all that one needs to do is look at the last ‘n’ digits of the number. If

Questions based on Punctuation marks have been asked in competitive exams frequently. These concepts are really important if you are looking at some of the banking exams or exams like SNAP. It is a good way to check a person's 'Verbal Ability'. With the help of my friend Sanket, I have a compiled a set of some examples followed by some previous year questions that can help you understand the concept better.

Words with Similar Meanings and Subtle Differences

March 21st, 2020 by

In the series on confusing words (Part 1, Part 2 and Part 3) we looked at words that sound similar or look similar but mean different things. There is another class of words you should be careful about - these are words that are often used interchangeably (and wrongly at that, I must add). This generally leads to bad writing than bad comprehension when used. You do not need to look far away for instances of not knowing the difference between these similar sounding words. Just ask any MBA aspirant whether have any preferences for specialization and a lot of them say ‘Marketing’. Just fol

How to Effectively Tackle Jumbled Paragraph Questions

March 17th, 2020 by

Sentence rearrangement or Jumbled paragraph questions have been a regular feature in the Verbal Ability section of the CAT. In this question type 4-5 sentences are given in a random order without any indication of the introductory or the concluding sentences. The sentences, when logically reorganized, form a coherent paragraph. This question type can be quite difficult since the subject matter and the sentences in which they are contained are often dense and complex. At times, the sentences can be lengthy and the theme esoteric or scholarly – something an average CAT aspirant is not v

4 Rules to Crack the Paragraph Completion questions in the CAT

February 28th, 2020 by

No other question in the CAT is as deceptively simple as Paragraph Completion questions. Superficially, they do not require us to know or remember any rules. They, in fact, require us to do something far more difficult – to think like the writer. Since the last week’s post on Parajumbles, I have been thinking hard over an appropriate parallel to explain the process of solving Paragraph Completion question. And all my thoughts end once again at the same point – Sherlock Holmes. Indeed, picking up the scattered clues, and building them into a clear chain of reasoning for anticipati

Skills to Acquire at a B-School to Thrive in the ongoing Gig Economy

February 15th, 2020 by

There was a time when a job was something one would get in for life. Even if one would change jobs a few times, the target would be to remain loyal to one firm for as long as possible. Even the changes would be within the sector. Then we witnessed the period when options increased, so it was easier for people to move jobs. Now, we have moved on to yet another stage of employment trends, where people continue to remain loyal to companies, but not just to one at a time. The entire ecosystem is known as the Gig Economy. The term gig economy originates from rock bands and their guitarists,

February 14th, 2020 by

You got to admit - spending two years at a Bschool (or one year, if you study at ISB, Great Lakes etc.) will surely rank amongst your best academic experiences. From participating in multiple events, putting all-nighters before exams, forging amazing friendships, and getting the kick of THAT one dream job placement, your B-school journey is something that will stay with you for the rest of your lives.

Personal Interview Skills

January 31st, 2020 by

In this post I would like to cover some of the basic ideas about personal interviews. Since brevity is the soul of wit, and tediousness the limbs and outward flourishes, I will try to be brief. Whom do the interviewers select? The candidate they “like” – so your job is to be “liked” by the panel. Attributes that normal panels like: Honesty Be ruthlessly honest with your answers You should know your subject You should understand your immediate environ Your answering should demonstrate analysis Listen to the words and the body language Answer the question asked Pane
