    #31. International Solar Alliance and its structure

    This should be easy. Also – read upon the Dr.V’s tikdams that you could have easily excluded the second statement (which boasts of including all UN countries)

    IAS pre 2016 by Tikdams

    Pretty standard static question

    https://www.civilsdaily.com/what-is-aqi/

    https://www.civilsdaily.com/astrosat-launch-india-reaches-stars/

    #38. “Araghatta” – what does this word mean?

    Static question but looks quite difficult to guess!

    #21. Purpose of Gold Bond Scheme/ Gold Monetisation Scheme?

    #23. Pradhan Mantri MUDRA Yojna. What about it?

    Pradhan Mantri Mudra Yojana: Funding the unfunded

    #24. Shale gas reserves found in which region?

    It’s a static question – relates to resources and distribution but do you remember one related question being asked a few years back – gaur gum exports to US (for shale gas).

    Wait for the answer keys by Dr. V

    #25. Global Financial Stability Report is prepared by?

    Hope you got this one. IMF does it. We had pushed a timely blog on this because UPSC is invariably putting one such question every year.

    https://www.civilsdaily.com/international-organizations-reports/

    #26. Regarding Atal Pension Yojna – which of the following statements are correct?

    We covered the scheme categorically here but to be fair, some of you might have found this one difficult (to affirm the statements, line by line). We will wait for Dr. V to comment more.

    #27. RCEP appears in context of which group of countries?

    ASEAN, what else?

    What is the significance of RCEP for India?

    #28. Where can you find BEE Star ratings?

    This is a common sense question – You would find these ratings in everything that uses electricity (Small or big labels). But still – should you be curious as to why UPSC veered towards it – here’s a hint from a newly established EESL

    https://www.civilsdaily.com/learn-about-energy-efficiency-services-limited-eesl/

    #29. India and the significance of International Thermonuclear Experimental Reactor

    We did not cover this – but this news has its root dating back to 2014

    Static stuff.

    #11. India’s first National Investment and Manufacturing Zone set up in?

    Ah! This is too much – we had nothing for you here. And we wonder if anyone did remember the states in order?

    We did briefly touched upon NIMZ while we were discussing TADF here – But no mention of states in any order.

    Technology Acquisition and Development Fund (TADF)

    #12. What’s the purpose of District mineral Foundations in India?

    This news came way back in May, 2015

    #15. What’s common among Ajanta and Mahabalipuram?

    #16. What do you know about Bitcoins?

    This should be easy to attempt. Central Banks are clueless. Not all of them have acknowledged it as a currency and so they can’t track it officially.

    https://www.civilsdaily.com/what-are-bitcoins/

    #17. New Development Bank – All about its establishment

  • Analysing the IAS Prelims 2016 | Current affairs heavy | Q1-10

    Hello,

    This is a very quick analysis of the Paper 1 – IAS Prelims 2016 which just went by. A Civilsdaily user tipped us about the heavily current affairs inclined IAS Prelims this year and we couldn’t stop digging into the Civilsdaily archives.

    We haven’t heard from most of you guys but we hope that if you kept up with daily newscards – you should have remembered context regarding most of these factual questions asked out from daily news.

    NOTE: This is not a blog post on answer keys. We will wait for Dr. V or UW to come up with detailed solutions and analysis. This is only an analysis of current affairs questions.


    #1. What’s Doctors without borders or Médecins Sans Frontières?

    • Context: Issue of pharma IPRs in ongoing Regional Comprehensive Economic Partnership (RCEP) negotiations
    • Médecins Sans Frontières (MSF) has warned India that it will no more remain ‘the pharmacy of the developing world’ if the proposals in the pact are adopted
    • An international humanitarian-aid non-governmental organization (NGO) and Nobel Peace Prize laureate

    Scroll down this story link:

    Regional Comprehensive Economic Partnership (RCEP)

    #2. The initiative called TEEB. What’s that?

    No idea. It was briefly mentioned in a pib release but such singular events are very hard to focus on and remember – http://pib.nic.in/newsite/PrintRelease.aspx?relid=123641

    #3. Red sanders in the news

    We had extensively covered this theme under our #back2basic category.

    https://www.civilsdaily.com/everything-you-want-to-know-about-the-red-sanders-12/

    https://www.civilsdaily.com/everything-you-want-to-know-about-the-red-sanders-22/

    To give you context into why red sanders were in news? This was the main card

    https://www.civilsdaily.com/operation-sesha-dri-ropes-in-17-nations/

    #4. Proper design and effective implementation of UN-REDD+ program can do what?

    The difference between REDD and REDD+ should have helped you answer this question. It is a pretty static one but still, explained here by Dr. V

    UNFCC to Paris Via Kyoto

    #5. Greenhouse Gas Protocol. What’s that?

    I think we missed this one. But this is what it is –

    The Greenhouse Gas Protocol (GHGP) provides accounting and reporting standards, sector guidance, calculation tools, and trainings for business and government. It establishes a comprehensive, global, standardized framework for measuring and managing emissions from private and public sector operations, value chains, products, cities, and policies.

    http://www.wri.org/our-work/project/greenhouse-gas-protocol

    #6. Financial Stability and Development Council. What’s that?

    We discussed about this very briefly when we were writing on Annual Budget articles (with infographics)

    The context for discussion was the creation of a Financial Data management centre which was est. under FSDC

    Remember this?

    Discussing Budget 2016-17 | Financial Sector Reforms

    #7. Agenda 21. Sometimes seen in news?

    This form a part of static syllabus. A quick reference primer was written here by Dr. V

    2. Agenda 21 <21 is agenda for 21st century, UNCCD was the result of direct recommendation of Agenda 21>

  • Agam Jain: Securing AIR 133 in UPSC 2015 despite all odds. Arise, Awake!

    source

    Background: An engineer who graduated from Mangalayatan University, Agam Jain managed 133rd rank in UPSC-2015. He lived in a village near Aligarh and that’s where it all started. In his first year of college, he used to go 4 km every day to teach poor children in another village and lived in adverse of the conditions.

    There was lack of electricity, water, cooler and other basic amenities. Even the main road was nearly 2 km away from his room. With that he experienced something which most youth in present day doesn’t face. He saw people living together without formalities, festivals (though with many superstitions) celebrated in enjoyment, beauty of flora and fauna at their best, changing seasons to evening walks on the trails near agriculture fields.

    He even saw some fights and deaths, ‘dangals’ as the best form of sports, people indulging in illegal activities and gender inequality.

    By the third year, he found that his study tactics and his desire to work for nation could only be met with entering the civil services. After that he used to go to the library to understand an article of Hindu – in complete one hour!

    Played volleyball a lot, analysed things more vividly and studied anything which came in his way. An average student, with a strong will power, he managed to climb the ladder of success, with perseverance.

    His journey: After graduation, he went to Delhi, made the timetable for complete one and half year and prepared exactly according to that.

    Short term strategy: One should make online as well as written notes. When you like any answer/topic from just copy (but selectively) them into your account under particular heading. These notes come handy everywhere like while travelling, sitting with some boring relatives etc.

    Newspaper cuttings: When you read newspaper/yojana/kurukshetra, cut the selective portion and put in file. Write when you listen to particular topic from air news, RSTV programs, read any book etc.

    Schedule: Make a schedule for 6 days a week. Reserve 7th day for revision of the on/offline notes. Don’t just revise them but minimise them, say from 2 pages to one and then to half by the time exams come.

    Prelims Strategy: Don’t leave anything undone when it comes to prelims.

    Besides preparing basics from the textbooks, one day he made a list of such vague things like name of national parks, rivers, GI tags, republic day tableau, international conventions and reports, recent Padma winners, UNESCO sites, programs under ministries etc.

    However, he suggests not to make the list in a day, for it will be hectic and can’t be remembered. Rather, one should have an eye on newspaper when something comes related to it.

    Polity gives edge in prelims, so one should not lose any mark in that portion. Read Laxmikanth as many times. Geography can be done easily too. One can check science monitor program of RSTV for current scientific developments.

    Mains Strategy: Writing practice is must. It gives an extra margin of few seconds per question which is very important.

    Tips regarding writing: Write answer in morning and evaluate yourself in evening. Don’t evaluate immediately. In evening, check the answer with the mind-set of teacher and do strict marking. This way, you will realise what teacher wants.

    Make list of some international conventions/charters etc., they help in beautifying the answer. Example, if one student writes, ‘India is trying best to stop child trafficking’, and another writes according to so and so convention, India is signatory to stop child trafficking on global level, it will make a significant remark on the examiner.

    Follow balanced approach.

    Tips to aspirants: Always keep a small paper with you. At times, while reading, we don’t know something and we think that we will search it later. But later, we used to forget that. That small paper could be used to note all those doubts which are to be resolved later.

    Don’t fool yourself. At times, we watch documentaries or other war related movies and tell ourselves that we are doing something related to studies. They might be related but vaguely and consuming precious time.

    Choose your material carefully and stick to that. If it is Laxmikanth, then don’t give damn to D D Basu. If it is Guha, then don’t care of Bipin Chandra and so on.

    If time permits, read some non-fictions (not directly related to upsc) in leisure time. He read Pax Indica by Shashi Tharoor; Makers of modern India by Guha; Brief History of time by Hawking etc. These will give you an extra edge somewhere unknowingly.

    Don’t spread the word of your preparation a lot. It might bring extra pressure on you.

  • Last Day Before Prelims

    And just like that D day is finally upon us.

    Most of you would be wondering what gyaan can I give you a day before the exam. And frankly there is nothing much to say. Just a few general things I wanted all of you to know. As time is of utmost essence I will keep the post very short.


    First thing first, don’t panic – Trust me you all know enough to score 110+ in 2015 type paper or 100+ in 2014 like paper but all of you won’t score that much. You would make mistakes. So onus is upon you to make sure you give your best. And you can give your best only if you don’t panic.

    But that does not mean, you should experience no arousal, no anxiety. Optimum performance is achieved only in the zone of optimum arousal.


    Think of a stage artist, he generally performs much better in front of live audience than he does sitting at home. Audience gives him that necessary arousal. Similarly exam setting must give you that kick that takes your performance higher than what you achieved in mocks.

    After that it’s important to be ready for the exam –So don’t wait for the evening and –

    • get your admit card printed if you have not already
    • Read all the instructions carefully and
    • arrange all the necessary stuff – ball point pen of required colour, photographs, id card, watch, chocolates, cashew, almonds etc.
    • Finalize your attire – comfortable and also the one which makes you feel good about yourself.
    • Finalize your transport arrangement and the timings ( leave well before time)

    What to do in the day and night

    • Simple revise, revise, revise.
    • Do not discuss, do not argue.
    • Firstly revise the mistakes you had made in the various mock test papers.
    • Current affair notes of yours
    • Curry affairs – science – tech and international – June to Feb
    • Spectrum – modern India summary of chapters
    • Just flip through the pages of 2 NCERTs of geography – look at all the maps
    • Polity and ecology titbits
    • Economy solved papers –
    • go through economics concepts simplified bundle very quickly – don’t take more than an hour
    • Any other thing you find important

    This should fill up your day.

    Go to bed early at night. Have a good night of sleep. I know it can be difficult but at least lie down on the bed with your eyes closed and do not get up.

    Check your stuff once again in the morning. Leave for the centre well before time.


    In the exam hall –

    • Fill up your details correctly
    • Don’t argue with invigilators
    • 2 hours is more than enough for general studies paper – so don’t worry about the time ‘- fir bhi do analyse where you are after half an hour
    • Don’t target a specific number of marks or attempts
    • In the 1st go of half an hour or so – mark all those you are sure of
    • Then start using all the tikdams, logical guesses, elimination – everything we learnt with utmost caution
    • Don’t be too conservative in your marking – but don’t make blind guesses
    • Read questions carefully and options even more carefully
    • Fill up your OMR sheet with even more care
    • Come out of the exam hall cheerful
    And just like that you will ace the paper 1

    CAST apne aap sambhal loge 

    Always remember

    Let it be known to everyone, how badly you want this service.

    I wish you all the very best for the exam. Go there – express yourself.

    6  Fruits stored in a cold chamber exhibit longer storage life because

    1. exposure to sunlight is prevented
    2. concentration dioxide in the is increased of carbon environment
    3. rate of respiration is decreased
    4. there is an increase in humidity
    • For longer shelf life, metabolic rate is to be reduced
    • Decreased rate of respiration helps in that
    • Increase humidity, high co2, exposure to sunlight is crap. It can be achieved in other ways also without needing cold chamber
