Directions for the following 2 (two) items:

Read the following passage and answer the items that follow. Your answers to these items should be based in the passage only.

The Indian middle class consist of so many strata that it defies categorisation under a single term class, which would imply a considerable degree of homogeneity. Yet two paradoxical features characterise its conduct fairly uniformly; extensive practice and intensive abhorrence of corruption. In the several recent surveys of popular perceptions of corruptions, politicians of course invariably and understandably top the list, closely followed by bureaucrats, policemen, lawyers, businessmen and others. The quintessential middle class, if teachers do not figure high on this priority list, it is not for lack of trying, but for lack of opportunities. Over the years, the sense of shock over acts of corruption in the middle class has witnessed a steady decline, as its ambitions for a better material life have soared but the resources for meeting such ambitions have not kept pace. What is fascinating however is the intense yearning of this class for a clean corruption less politics and society, a yearning that has again and again surfaced with any figure public or obscure, focus on his mission of eradicating corruption. Even the repeated failure of this promise on virtually every man’s part has not subjected it to the law of diminishing returns.


Q.31) The intense Middle Class intensely yearns for

  1. better material resources
  2. better material resources
  3. clean honest society
  4. law of increasing returns


Q.32) Teachers are not high on the list of corruption because they do not have

  1. courage
  2. opportunities
  3. support
  4. ambition

Q.33) The salaries A, B, C are in the ratio 2 : 3 : 5. If the increments of 15%, 10% and 20% are allowed respectively in their salaries, then what will be new ratio of their salaries?

  1. 3 : 3 : 10
  2. 10 : 11 : 20
  3. 23 : 33 : 60
  4. Cannot be determined

Q.34) What is the speed of the train?

Statement I: The train crosses a signal pole in 18 seconds.

Statement II: The train crosses a platform of equal length in 36 seconds.

Statement III: Length of the train is 330 metres.

  1. Statement I and II only are sufficient
  2. Statement II and III only are sufficient
  3. Statement I and III only are sufficient
  4. Statement III and either Statements I or II are sufficient

Q.35) A person covered a distance from P to Q at a speed of 40 kmph. On the return journey, he covered three-fifths of the distance in two-third of the time he took to cover from P to Q. At what speed should he travel to complete the remaining journey from Q to P, in the remaining time?

What IMPACT can the ‘60 Day’ have on the final results? We will explain by taking a small example. Imagine you are sitting in the examination hall, appearing in Prelims Paper I. You have attempted 70 questions already but still unsure about a few. Then you stumble upon a question that was asked in 60 Day (and believe us, it has happened to hundreds of students countless times). You choose the right answer and submit your paper hoping for the best! Eventually, you go on to clear Mains as well as Personality Test and secure a good rank as well. When the cut off gets announced by UPSC, you realize that you have scored just one mark more than the cut off! Yes, that one mark can change your life (and it has done so to many of our students in the past). Now, imagine the kind of impact 60 to 80 marks can have! Isn’t that so fascinating to imagine?  

One’s level of preparedness is always different for different subjects. Even within a subject, one’s comfort level may vary with topics. For example, one might be more comfortable in solving questions of Polity than Economics and within Polity also, one might be at ease with questions on fundamental rights than Parliament. The level of comfort and ease that one has with a subject/ topic gets manifested in the examination. However, there is no conscious effort by aspirants to micro analyze these aspects. Now, coming to the second aspect i.e. the mistakes that one commits in answering MCQs, it can be said that there are mainly four reasons behind incorrect responses in the OMR sheet. They are:

  1. Lack of information
  2. Lack of analytical ability
  3. Silly mistakes
  4. Excessive risk-taking

Let’s analyze them one by one:

  1. Lack of information: You simply don’t know the information. You are clueless and that’s why you don’t attempt the question. For example, you may have never come across a regime called the ‘Wassenaar Agreement’ during your preparation and you can’t do much about it. The lack of information is pardonable and rectifiable. You can read more and gather more information. That is within your reach.
  2. Lack of analytical ability: You know the concept but the question is a twisted one and you are not able to apply the concept. For example, in a question asking you to identify the climate type of a region based on certain given parameters like precipitation, temperature, and air density, you might find it difficult to mark the correct option even if you are aware of all the options given in the question! That is clearly a lack of application and you can overcome it by developing a habit of framing questions in your mind while you study any topic.
  3. Silly mistakes: This habit is unpardonable. You know the concept, you become happy, you misread the question, you mark the incorrect answer and you are out of the race! Such mistakes reveal your hurriedness while answering the question. A simple mistake of reading ‘chose the incorrect option’ as ‘chose the correct option’ can destroy your chances. It means that you need to have patience and focus while attempting the paper.
  4. Excessive risk-taking: You are confused between the options and just in order to increase your attempts, you make wild guesses and try your luck only to repent eventually. Risk-taking is an art and one must be very careful while doing the guesswork in confusing questions. If you are not lucky enough, it can spoil your chances.

You will realize that these problems will have different meanings for different people. For example, one might find a lack of information as the main culprit in answering wrong the questions on Culture while in Polity, lack of analytical ability is usually the culprit. The point here is that you must analyse your preparation on these yardsticks by applying them on different subjects/ topics. If one is having a headache, he/ she can’t have the same medicine for fever. Isn’t it.

This is where our revamped ’60 Day’ comes into the picture. It will give you an opportunity to micro analyze your preparation and perform better in the examination.

Finally, it is up to you to take advantage of this framework. We are sure of only one thing- if you follow this program, assess yourself on the basis of the given framework and keep improving your weaker areas, success will be yours.

We are providing you with the right platform, the right guidance, and the right competition. Do you have the right motivation to make full use of this initiative? We think you have. Come, be a part of this initiative and take the first step towards SUCCESS!

Importance of self – tracking:

We could have provided all of you with login id and passwords to monitor your daily performance in the 60-day program.

Instead, a simple and most beautiful way which Disqus provides is profile based commenting!

Yes, we have seen the most successful candidates who have taken the maximum benefit from this program monitoring themselves by commenting on their answers in the box given (Disqus comment). And reviewing their performance themselves once in 10 days on the progress meter.
