TNPSC Constitution practice questions: features and amendments

By the PrepMatic team · Updated 9 Oct 2026 · 4 min read

Indian Polity is Unit IV of the General Studies paper and carries about 15 of the 75 questions in both the Group 4 and Group 2 prelims papers (TNPSC calls the unit-wise split "indicative"). The Constitution itself, meaning how it was made, what it borrowed, its Schedules and its amendments, supplies the easiest marks in that unit. Try the five questions below, check the reasoning, then use the revision tables. The wider subject guide is TNPSC Indian Polity.

What this topic covers

• Making of the Constitution: the Constituent Assembly (first met 9 December 1946, with Dr Rajendra Prasad as president), the Drafting Committee under Dr B. R. Ambedkar, adoption on 26 November 1949 and commencement on 26 January 1950.
• Sources of the features: which constitution each idea came from.
• Structure: Parts, Articles and the 12 Schedules.
• Amendments: the procedure under Article 368 and the amendments that changed something you can name.

At SSLC standard, most questions ask for a date, a person or a name. Questions that ask you to reason about a provision are rarer, so accurate recall pays.

Answers and explanations

1. C. The Constitution was adopted on 26 November 1949 but came into force on 26 January 1950, which is why Republic Day falls on that date. 15 August 1947 is Independence Day and 9 December 1946 is the first meeting of the Constituent Assembly.
2. A. Dr Ambedkar chaired the Drafting Committee. Dr Rajendra Prasad presided over the Assembly itself, and B. N. Rau was its constitutional adviser.
3. D. Canada's constitution gave India the model of a federation with a strong Centre and residuary powers with the Union. The Concurrent List comes from Australia, and Directive Principles from Ireland.
4. B. The Tenth Schedule, added by the 52nd Amendment in 1985, deals with disqualification on grounds of defection. The Eleventh and Twelfth Schedules list the subjects of panchayats and municipalities.
5. C. The 61st Amendment (1988) lowered the voting age to 18. The 42nd and 44th Amendments are connected with the Emergency period, and the 73rd with panchayats.

How to prepare the Constitution chapter

Learn the amendments as a short table rather than a long list. These are the ones that recur.

Three habits help. First, pair each amendment with a number you will remember, such as "42nd means the Preamble". Second, learn the Schedules by theme: Seventh is the three lists, Eighth is languages, Tenth is defection. Third, revise the borrowed-features table the night before a mock test, because it is pure recall and quick to refresh.

For the Preamble and rights, move on to TNPSC Preamble and Fundamental Rights practice, and for the next unit-level view read the Group 4 syllabus.
