Hello Friends, 

ARCHIVES OF 60 DAYS

NOTE: 

Let us pledge to make it a big game-changer (better than last year) in the next 60 days! 

Note- Download the OMR Sheet and attempt the questions exactly like UPSC Prelims. After you are done, please post your OMR in the comment section. Once the solution key is released (around 5 PM), cross-check the answers and, comment the marks (you scored) in the same comment thread. This will keep you accountable, responsible and sincere in days to come. 

You can also take part in the discussion with peers.

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

The whole biosphere, like the individual organisms that live inside it, exists in a chemically dynamic state.  In this homeostatic system, a great number of organic compounds are synthesized, transformed, and decomposed continuously; together, these processes constitute the major parts of the carbon cycle.  For the smooth operation of this cycle, degradation is just as important as synthesis:  the green plants produce great quantities of polymers, such as cellulose, and innumerable other compounds like alkaloids, terpenes, and flavonoids, that green plants cannot use as sources of energy during respiration.  The release of the carbon in these compounds for recycling depends almost entirely on the action of both aerobic and anaerobic bacteria and certain types of fungi.  Some bacteria and fungi possess the unique and extremely important biochemical asset of being able to catalyze the oxidation of numerous inert products, thereby initiating reaction sequences that produce carbon dioxide and so return much carbon to a form that actively enters into life cycles once again.

Q.33) The passage contains information that would answer which of the following questions about the carbon cycle?

  1. What are some of the compounds that are broken down in the carbon cycle?
  2. Why are some compounds that are involved in the carbon cycle less reactive than others?
  3. What role do bacteria and fungi play in the carbon cycles?

Choose the correct code

  1. 1 only
  2. 2 only
  3. 1 and 2 only
  4. 1 and 3 only

 

Q.34) Which of the following is the primary reason that degradation is as important as synthesis to the smooth operation of the carbon cycle as implied by the author?

  1. Most of the polymers and organic compounds found in the plant kingdom are chemically unstable.
  2. The synthesis of some organic material deprives life processes of an energy source.
  3. Decomposition permits the recycling of carbon that would otherwise be fixed in certain substances.
  4. Many organisms cannot use plants as a source of food, but can feed on bacteria and Fungi.

 

Q.35) The author’s contention about the importance of bacteria and fungi in the production of energy for life processes would be most clearly strengthened if which of the following were found to be true?

  1. Both aerobes and anaerobes provide sources of energy through the decomposition of organic material.
  2. Most compounds containing carbon are unavailable as energy sources except to some bacteria and fungi.
  3. Bacteria and fungi break down inert material in ways that do not involve oxidation.
  4. Many compounds remain inert, even in the presence of bacteria and fungi.

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.
