UPSC CSE Prelims 2023 Detailed Solutions

Detailed Prelims 2023 solution with reference to authentic sources. Thoroughly cross-checked and refined.


We took our time in publishing this detailed solution because this year, more than others, there were a lot of complex questions. We have tried our level best to give you authentic sources to justify why we think a particular answer is correct.

Yet despite our best efforts, there are some question which are just weird. We have left multiple options in the answer key for those.

We wish you luck in your UPSC journey.

Estimating Difficulty Levels

Easy - given directly in basic books or NCERTs (34 Q)

Medium - concept given in basic books needs to be applied (36 Q)

Hard - Worth skipping in actual paper (30 Q)

If you're only interested in the Answer Key, go here.


Prelims 2023 Cutoff Prediction

We have estimated a cutoff based on two methods.

  1. Difficulty level assessment of the GS paper.
  2. Data collected from social media handles via this form.

These two methods would serve to cross verify our finding so that we can give a more robust prediction. Further, we have also adjusted the cutoff keeping in mind the difficulty of the CSAT exam, which we feel will push the cutoff lower.

Method 1 - Estimating Difficulty

Easy Medium Hard
Questions 34 36 30
Accuracy 0.8 0.6 0.3
Positive 54.4 43.2 18
Negative -4.5 -9.6 -4
Total 49.9 33.6 4

Total Marks = 87.5

But this is when you're attempting all 100Qs. So cutoff, once we adjust for number of questions attempted and difficulty of CSAT falls below this.

Cutoff Predicted: 80-85 Marks.

Method 2 - Form Data

Entries received: 3052

(About 900 entries were removed from the data. Reasons: failing in CSAT, assumed 50% success rate for border case candidates, and bogus entries)

Mains candidates: 12,000

People sitting for Prelims: 5,00,000

Cutoff should be at the 97.6th percentile score from the data collected.

Cutoff Predicted - 82-84 Marks.


A Note on Controversial Questions

We have highlighted most of the questions where disagreements exist in the answer keys of various institutes. You can simply ctrl+F "controversial question" and you will find them.

The problem lies in third statement where both Finance Bill and money bill are mentioned together, creating a room for doubt that Finance Bill here refers to Financial Bills under Article 117(1) and Article 117(3).

Compliance report of CAG

(https://cag.gov.in/webroot/uploads/download_audit_report/2016/Union_Civil_Compliance_Report_27_2016_Full.pdf)

A Finance Bill is a Money Bill as defined in Article 110 of the Constitution. Whereas a Financial Bill is an ordinary bill as it apart from dealing with money matters also deals with non-money matters.

  • It deals with the proposals of the government for levy of new taxes, modification of the existing tax structure or continuance of the existing tax structure beyond the period approved by Parliament are submitted to Parliament through this bill. So, it is introduced as a part of the Annual Financial Statement (i.e. Budget) under Article 112.
  • The Finance Bill is accompanied by a Memorandum containing explanations of the provisions included in it. The Finance Bill can be introduced only in Lok Sabha.
  • However, the Rajya Sabha can only recommend amendments in the Bill. The bill has to be passed by the Parliament within 75 days of its introduction. So, statement 1 is not correct and statement 2 is correct.
  • Statement 3 is not correct: As a finance bill is a money bill so no joint sitting of the two houses is allowed with regard to a finance bill under Article 108.

Ans: B

Difficulty: Medium

Subject: Economy

Solution: The concept of “Small Farmer Large Field” refers to the idea where many marginal farmers in a particular area come together and organize themselves into groups. These groups work collectively to synchronize and harmonize selected agricultural operations.

In this approach, instead of individually working on their small plots of land, these farmers pool their resources, knowledge, and efforts to cultivate larger fields collectively. By doing so, they can achieve economies of scale, improve efficiency, and enhance productivity.

This concept allows small farmers to overcome the limitations of their individual small land holdings and collaborate to optimize their agricultural activities. It can involve sharing equipment, sharing labor, collectively marketing their produce, and adopting modern farming techniques.

Ans: B

Difficulty: Easy

Subject: Economy

Solution:

Statement 1 is correct: History of SHGs in India-

In India, banks are the predominant agency for delivery of micro-credit. In 1970, Ilaben Bhat, founder member of ‘SEWA’ (Self Employed Women’s Association) in Ahmadabad, had developed a concept of ‘women and micro-finance’. The Annapurna Mahila Mandal’ in Maharashtra and ‘Working Women’s Forum’ in Tamilnadu and many National Bank for Agriculture and Rural Development (NABARD)-sponsored groups have followed the path laid down by ‘SEWA’. ‘SEWA’ is a trade union of poor, self-employed women workers.

Since 1987 ‘Mysore Resettlement and Development Agency’ (MYRADA) has promoted Credit Management Groups (CMGs). CMGs are similar to self-help groups. The basic features of this concept promoted by MYRADA are: 1] Affinity, 2] Voluntarism, 3] Homogeneity and 4] Membership should be limited to 15-20 persons. Aim of the CMG is to bestow social empowerment to women.

In 1991-92 NABARD started promoting self-help groups on a large scale. And it was the real take-off point for the ‘SHG movement’. In 1993, the Reserve Bank of India also allowed SHGs to open saving accounts in banks. Facility of availing bank services was a major boost to the movement.
