Mains Accelerator Combo [MAC] : Inheritability

Inheritability: When a subtopic inherits the properties of the parent topic

We know it sounds complex. Let us break it down for you

UPSC Syllabus is hierarchal in nature i.e. we have subjects > Topics > Sub topics > Sub-sub Topics etc. In simple terms, Principle of Inheritability dictates that “content for a sub-topic can be derived from its parent topic.

Lets take “Institutions” as an example. The Polity under GS 2 mentions this topic

Appointment to various Constitutional posts; Constitutional Bodies (powers, functions and responsibilities); Statutory, Regulatory and Quasi-judicial bodies

Current Structure Looks Like this

Syllabus hierarchy: Level 0 GS 2, Level 1 Polity, Level 2 Institutions

acads has compiled entire topic under “Institutions”. It has various sub-topics under this — CAG, NHRC, SHRC, CIC, CBI, NCSC, NCST, NCW, NCM, SOLM, HC, SC etc.

The structure after inclusion of various bodies becomes

Syllabus hierarchy: Level 0 GS 2, Level 1 Polity, Level 2 Institutions, Level 3 CAG, NHRC, SHRC, CIC, CBI, NCSC and others
Inheritability diagram: Polity at level 1, constitution, institutions, governance and judiciary at level 2, bodies at level 3, with 3D4C

On the face of it, all these bodies might look entirely different. However, the answers to questions based on these topics follow a common theme. This common theme can be used to structure, substantiate and present an above average answer on any of these bodies

Using Inheritability, we know that this common theme for CAG/SHRC etc. (level 3) is derived from Parent Topics which are Polity (level 1) and Organizational Bodies/Institutions (level 2)

Below are 2 questions from CSE 2014 and 2017

  • Is the National Commission for Women able to strategize and tackle the problems that women face at both public and private spheres? Give reasons in support of your answer CSE 2017
  • National Human Rights Commission (NHRC) in India can be most effective when its tasks are adequately supported by other mechanisms that ensure the accountability of a government. In light of the above observation assess the role of NHRC as an effective complement to the judiciary and other institutions in promoting and protecting human rights standards. CSE 2014

Using Inheritability we can form a template/structure for above questions using level 1 and level 2. Please see the table below.

Template: common Polity points at level 1, institution points (mandate, selection, function) at level 2, and NHRC or NCW specifics at level 3

Don’t worry if you are unable to understand the table. acads MAC will take care of it!

Thus using “inheritability” aspirants can write an excellent answer within time limits and this extra time can be used in other difficult questions.

It’s never the lack of content that is responsible for an aspirant’s low marks in mains. It’s always the lack of ability to use your content to the maximum.

acads MAC leverages multiple techniques like Inheritability, Replicability, 3D4C, Lego methods etc. to ensure that our learners can score maximum by reading minimum.
