Prologue

This article series deals with how to handle India 2014 || Bharat 2014 (+12th Five year plan + sample MCQs).

So far we are done with

  1. ch1 (land and people), ch30 (state and UT) click me
  2. ch12 (Environment and Forest) click me
  3. ch11 (Energy) click me

Now time for the Ch25 Science Tech. It’s the biggest hathodaa (hammer) chapter in India yearbook. Once you overcome this one, remaining chapters are halwaa.

Prerequisite: NCERT- Science

India Yearbook Science-tech studyplan

Use the NCERTs as the base material, in following order:

ClassChapters (PHYSICS)ChemistryBiology
74, 13, 14 and 155 and 61,2,10,11 and 12
811 to 163 to 62, 8, 9 and 10
98 to 121 to 45,6,7 and 13
1010, 12 and 131 to 56 to 11
11Physics textbook ch.1****
12****Biology textbook Ch.11 and 12

** If you observe the answerkey of CDS (I) 2014 paper, UPSC has asked quick a few tough questions from Class11-12 science NCERTs. (Twelve MCQs from from 7-10 and Eight from 11-12).

Moral of the story is: one should selectively read Class11-12 science NCERTs for CSAT-2014, as an Insurance policy against any BackbreakingTM Move.

After NCERT, go through following articles on Mrunal.org/SNT

  1. [Space Tech] Current Affairs Compilation 2012-13 for SSC CGL, UPSC CSAT
  2. [Defense] Current Affairs compilation 2012-13: missiles, joint exercises, operations, organizations
  3. [Public Health] Current Affairs 2012-13: Diseases, Drugs and Research (Part 2 of 3)

Some of their content is outdated, but the basics about space program, missile program etc. remain one and same, and should help you build the ‘base’.

Now, time to finish following chapters

IYBch 25 science tech (entire)
IYBch 9 Defense (only R&D related portion)
IYBch 8 Comm. & IT (only R&D related portion)
12th FYP vol1ch 8 Science
12th FYP vol1ch 9 Innovation

IYB Chapter 25 Science Technology

This chapter mainly talks about four things:

  1. Lot of HRD/fellowship/scholarships with catchy names. (not that important)
  2. Nuke Tech. we are already done with “Nuke Energy” part. Click me. Now we only see nuke-tech’s relevance to agro and healthcare.
  3. Bio Tech
  4. Space Tech

IYB Ch9: Defense (R&D Related)

Defense chapter mainly talks about three topics:

  1. IR / bilateral
  2. GK type (Army, Navy airforce- their ranks, entry schemes etc.)
  3. Sci-tech (missiles, technology, DRDO etc.)

First we focus on the third topic. But before that, do read following article

  3. D. Natural sweetener, Britannica
  4. D. Both wrong. It’s extracted from leaves, and plant native of S.America. (NIIR board)
  5. D. All correct, as per Tamilnadu State Agro portal
  6. D. All of them as per BARC page
  7. C. both statements wrong UC Davis university, California  (note: question asked you to find “Wrong” statements, hence C and not D)
  8. D. Both wrong. Bhabhatron is not a nuke reactor, but teletherapy device to help rural patients get treatment without having to travel to faraway cities.  And PACT program belongs to IAEA and not WHO.
  9. D. all wrong. These are supercomputers of BARC
  10. B. 1 and 3 are wrong. It is “in-vitro” and not “in-vivo” (IYB page 803.); ELISA is not a radioimmunoassay. (Naik’s Biochem book, Page433)

    Thanks for this article, i have one very imp questions for you

    In this coming Loksabha election which political party do you support and why??
    Plz give the answer because its very imp.for our future

    1. LOL.. How mrunal’s Answer is IMP for out Future ? So will you vote according to mrunal’s opinion ? C’mon man don’t vote for party, vote for correct person in your area. This way you can help correct person to be lawmaker.

      My comment means no disrespect for Mrunal sir.

    2. I ‘m completely agree with, rohan

    3. This is just an example of the political chaos in our country.. Vote on the merit of the candidate and past experiences of the constituency. Leaders of our country have successfully confused the voter among some trivial issues and nobody discusses the way ahead. Anyways. Do vote!
