RBI Grade B Precis Writing: How to Identify Core Ideas and Remove Unnecessary Details

The biggest challenge in RBI Grade B Precis Writing is often not English. It is selection.

Most aspirants can understand a passage reasonably well. The difficulty begins when they have to decide:

What should I retain, and what should I remove?

If you retain too much, the precis becomes lengthy. If you remove too much, the central meaning gets lost.

The solution is to learn how to separate core ideas from supporting details.

What Is a Core Idea in Precis Writing?

A core idea is a point that is necessary to understand the author’s main argument.

Suppose a passage discusses:

  • rapid growth of digital banking;
  • improved access to financial services;
  • examples such as mobile banking and UPI;
  • digital literacy challenges;
  • cyber fraud;
  • consumer protection; and
  • the need for safer digital-finance infrastructure.

The central message may be:

Digital technology can expand financial inclusion, but its benefits depend on digital literacy, security and adequate consumer protection.

That is the backbone of the passage.

Your precis should preserve this backbone while reducing the details surrounding it.

Step 1: Find the Central Message First

Before deciding what to remove, determine what the passage is fundamentally saying.

After your first reading, try completing this sentence:

“The author mainly argues that…”

If you cannot complete it in one or two sentences, read the passage again.

For example, a passage may discuss declining fertility, longer life expectancy, pension expenditure, healthcare and labour shortages.

Instead of treating these as unrelated points, identify the larger message:

An ageing population creates economic and social challenges that require appropriate policy responses.

Once the central message is clear, identifying supporting ideas becomes easier.

Step 2: Reduce Each Paragraph to One Core Point

During the second reading, ask:

“If I could retain only one idea from this paragraph, what would it be?”

Consider this paragraph:

Artificial intelligence can automate repetitive tasks, process large volumes of information and improve organisational productivity. Banks are increasingly exploring AI for fraud detection, customer support and risk assessment.

The core idea is not every individual application.

It can be reduced to:

AI can improve organisational productivity by automating tasks and supporting decision-making.

Fraud detection and customer support are examples. They may not need separate space in the precis.

Do this for every paragraph and you will gradually create the skeleton of the passage.

Step 3: Use the “Must Keep – Can Remove” Test

Divide information mentally into two categories.

Must Keep

Generally retain:

  • the central argument;
  • major causes;
  • major consequences;
  • important contrasts;
  • essential relationships;
  • major challenges; and
  • the author’s main conclusion.

Can Remove

Depending on the passage, you can often remove:

  • repeated explanations;
  • lengthy examples;
  • anecdotes;
  • quotations;
  • descriptive language;
  • minor statistics;
  • lists illustrating the same idea; and
  • secondary background information.

The key question is:

“If I remove this information, will the central meaning remain intact?”

If yes, it is probably a supporting detail rather than a core idea.

Step 4: Distinguish an Idea from Its Example

This is where many candidates lose control of the word limit.

Suppose the passage states:

Climate change is increasing the frequency of extreme weather events. Floods in one region, prolonged droughts in another and repeated heatwaves demonstrate the growing vulnerability of communities.

The core idea is:

Climate change is increasing exposure to extreme weather events.

Floods, droughts and heatwaves illustrate the argument.

You usually do not need to reproduce every example.

A precis retains the idea behind the examples.

Step 5: Look for Repetition in Different Words

Authors frequently reinforce an important point by expressing it in several ways.

For example:

Financial literacy helps individuals make informed financial decisions.

Later:

People with inadequate financial knowledge may struggle to choose suitable financial products.

These statements are closely related.

Instead of retaining both separately, you might compress them into:

Financial literacy enables individuals to make more informed financial decisions.

Precis Writing rewards your ability to merge overlapping ideas.

Step 6: Identify Cause-and-Effect Chains

Sometimes several sentences should not be treated as separate points because they form one logical chain.

For example:

Geopolitical Conflict -> Supply Disruption -> Higher Energy Prices -> Inflation -> Pressure on Household Budgets

Instead of retaining five disconnected statements, preserve the relationship:

Geopolitical conflicts can disrupt supply chains and raise energy costs, contributing to inflation and pressure on household finances.

This technique produces both compression and analytical clarity.

Step 7: Don’t Delete Important Qualifiers

Removing details does not mean simplifying the author’s argument until its meaning changes.

Suppose the original passage says:

Artificial intelligence may displace certain routine jobs while creating new opportunities in other areas.

A weak precis might say:

AI causes unemployment.

This is shorter—but inaccurate.

The original argument was balanced.

A better compression is:

AI may displace some routine jobs while creating new employment opportunities.

The goal is:

Remove unnecessary words, not necessary meaning.

A Simple Practical Example

Consider this short passage:

Digital payments have expanded rapidly because of improved connectivity, smartphones and payment infrastructure. They offer consumers faster and more convenient transactions and can support wider participation in formal finance. However, cyber fraud, low digital literacy and connectivity gaps can prevent some groups from benefiting fully. Expanding digital payments must therefore be accompanied by stronger consumer protection, awareness and reliable digital infrastructure.

Step 1: Central Idea

Digital payments can expand financial access, but supporting safeguards and infrastructure are necessary.

Step 2: Core Ideas

Growth of digital payments -> Benefits -> Challenges -> Required safeguards

Step 3: Details That Can Be Reduced

We do not necessarily need to separately explain smartphones, every benefit or every technological development.

Possible Precis

Title: Inclusive Growth of Digital Payments

Digital payments can improve convenience and participation in formal finance, but their benefits may be limited by cyber risks, inadequate digital literacy and connectivity gaps. Sustainable expansion therefore requires reliable infrastructure, consumer awareness and effective protection mechanisms.

Notice that the precis does not copy the original passage line by line.

It preserves its logical skeleton.

Use the “Core-Idea Skeleton” Before Writing

Before drafting your precis, spend a little time creating a skeleton such as:

Problem -> Cause -> Impact -> Challenge -> Response

or

Development -> Benefits -> Risks -> Safeguards

or

Issue -> Reasons -> Consequences -> Solution

The exact structure will depend on the passage.

Once the skeleton is ready, reconstruct the precis from it rather than repeatedly looking at the original wording.

This also helps you write more naturally in your own words.

What Should You Never Remove?

While reducing the passage, be careful not to eliminate:

The Central Argument

An Essential Contrast

A Major Cause

A Major Consequence

The Author’s Final Position

For example, if an entire passage discusses both the opportunities and risks of AI, retaining only the opportunities would distort the author’s message.

A shorter precis is not automatically a better precis.

Accuracy comes before aggressive compression.

A 5-Question Check Before Finalising

After completing your precis, ask:

1. What was the original passage mainly about?
Does my precis communicate that clearly?

2. Have I retained all major ideas?
Check whether any essential stage of the argument is missing.

3. Have I retained unnecessary examples?
Remove them if they do not add essential meaning.

4. Have I repeated the same idea?
Merge overlapping points.

5. Has compression changed the author’s meaning?
If yes, correct it immediately.

This short review can significantly improve the quality of your response.

How to Practise This Skill

You do not need to write a full precis every day.

Take a passage and practise only this:

Central Idea – 1 sentence

Core Ideas – 4 to 6 points

Details to Remove – 4 to 6 points

This exercise trains the exact skill many candidates lack: selection.

Once you can reliably distinguish the core argument from supporting material, full Precis Writing becomes much easier.

Final Takeaway

Successful RBI Grade B Precis Writing depends on knowing what matters and what does not.

Do not try to preserve every fact, example and explanation.

Instead, follow:

Central Idea -> Core Points -> Logical Relationships -> Remove Secondary Details -> Reconstruct

Your objective is not simply to make the passage shorter.

It is to preserve its essential meaning with minimum unnecessary detail.

For RBI Grade B 2027 preparation, this is also a skill worth diagnosing separately. If your precis repeatedly exceeds the word limit, the problem may not be vocabulary or typing speed—it may be that you are unable to distinguish essential ideas from supporting information.

That is exactly why the Bank Whizz approach follows:

Attempt -> Evaluation -> Diagnosis -> Correction -> Rewrite

Once you learn what deserves to stay and what can safely disappear, Precis Writing becomes considerably more controlled.
