Part 3: Speculating, Comparing and Justifying

Introduction: Master the "Big Picture" Conversation

Welcome to Part 3 of the IELTS Speaking test! If Part 1 is a chat about you and Part 2 is a short story, Part 3 is a serious discussion. This is where the examiner pushes you to see how well you can handle abstract ideas. You aren't just talking about your life anymore; you are talking about the world, society, and the future.

In this guide, we will focus on three "Power Skills" that examiners look for: Speculating (guessing about the future), Comparing (looking at differences), and Justifying (explaining why). Mastering these will help you move from a Band 5 or 6 to a Band 7 or higher.

The Marking Criteria: How You Earn Marks

To get a high score, you need to show the examiner more than just "okay" English. Here is how these skills affect your score:

1. Grammatical Range and Accuracy: Using "might" or "could" for speculation shows you can use complex grammar beyond the simple present tense.
2. Lexical Resource: Using words like "alternatively" or "consequently" shows you have a wide range of vocabulary.
3. Fluency and Coherence: Justifying your answers prevents short, "choppy" responses and keeps you talking longer, which is exactly what the examiner wants.

Skill 1: Speculating (Talking about "Maybe")

Speculating means talking about things you are not 100% sure about, especially the future or hypothetical situations. In Part 3, examiners often ask: "How do you think education will change in the next 20 years?"

Don't worry if you don't know the "right" answer! There is no right answer in IELTS. The examiner only cares about the language you use to guess.

How to do it well:

Instead of saying "I think..." for every sentence, use Modal Verbs and Probabilistic Phrases.

Weak Version (Band 5):
"Maybe schools will use more computers. Everyone will study at home. It is good."
(Too simple, repetitive grammar, very short.)

Improved Version (Band 7+):
"It is highly likely that traditional classrooms could be replaced by virtual reality. I imagine students might spend more time learning at home, although this is liable to reduce their social skills."

Useful Phrases for Speculating:

• "I would imagine that..."
• "It’s hard to say for sure, but I suspect..."
• "There is a strong possibility that..."
• "In the foreseeable future, we might see..."

Skill 2: Comparing (Past vs. Present or Group vs. Group)

Examiners love to ask you to compare things. For example: "How is the way people shop today different from the way they shopped in the past?" This is a test of your comparative structures.

The "Contrast" Strategy:

To get higher marks, don't just talk about today. Explicitly mention the difference using linking words.

Weak Version (Band 5):
"Today we shop online. In the past, people went to markets. Online is faster."
(Simple sentences, lacks "flow".)

Improved Version (Band 7+):
"In contrast to the past, when shopping was a social activity at local markets, modern consumers tend to prefer the convenience of online platforms. While the former allowed for physical interaction with products, the latter is significantly more efficient for busy people."

Useful Phrases for Comparing:

• "On the other hand..."
• "In comparison to..."
• "Whereas in the past..."
• "A striking difference between X and Y is..."

Skill 3: Justifying (Giving the "Why")

Justifying is simply backing up your opinion with reasons and evidence. If you say "I think cars are bad," you must explain why. This is the key to Coherence. A good justification often uses the "Because -> Example -> Result" chain.

The "Step-by-Step" Justification:

1. State your point: "I believe public transport is essential."
2. Give a reason: "This is because it reduces the number of vehicles on the road."
3. Give a result: "Consequently, air pollution levels in big cities can be lowered significantly."

Weak Version (Band 5):
"I think history is important. We can learn about old people. It's interesting."

Improved Version (Band 7+):
"I'm of the opinion that history is a vital subject primarily because it allows us to avoid the mistakes of the past. To illustrate, by studying previous economic crashes, governments can better prepare for future financial stability."

Useful Phrases for Justifying:

• "The main reason for this is..."
• "This can be attributed to..."
• "A clear example of this would be..."
• "This is why I feel that..."

Quick Review: The Part 3 "Pro" Checklist

Did you know? Part 3 usually lasts 4 to 5 minutes. If you give short answers, the examiner will have to ask more questions, which can feel like an interrogation! Longer, justified answers put you in control.

Check these off as you practice:
• Did I use a modal verb (could/might) to show I'm speculating?
• Did I use a linking word (whereas/on the other hand) to compare?
• Did I explain the "why" (consequently/due to) to justify my point?
• Did I avoid using "I" too much and talk about "people" or "society" instead?

Common Mistakes to Avoid

1. Being too personal: In Part 3, avoid saying "I like shopping." Instead, say "Many people enjoy shopping because..."
2. The "Short Answer" Trap: If you stop after one sentence, the examiner will wait for more. Always aim for 3-4 solid sentences.
3. Silence while thinking: If you need a second to think about a complex topic, use a filler phrase like, "That's a thought-provoking question, let me consider that for a moment..." This keeps your fluency mark high while your brain works!

Key Takeaway

Part 3 is your chance to show off your "academic" English. Use speculation to handle the future, comparison to show range, and justification to build logical arguments. Think of yourself as an expert being interviewed for a documentary—be formal, be detailed, and always explain your reasons!
