Scanning
Master the art of hunting for specific information — names, dates, numbers, and keywords — without reading every word.
Theory: What Is Scanning?
THEORYScanning is the technique of moving your eyes rapidly across a text to locate a specific piece of information — a name, date, number, or keyword — without reading everything around it. Unlike skimming (which gives you the big picture), scanning is targeted: you know exactly what you are looking for before you start.
Target Speed
Find a proper noun or number in a 700-word passage in under 30 seconds
Identify Anchor
Always identify your anchor keyword BEFORE your eyes move to the passage
Sentences to Read
Once you find the keyword, read 2–3 surrounding sentences carefully
Move On Rule
If you cannot find the answer after 90 seconds, guess and move on
Scanning vs Skimming — Key Differences
| Feature | Skimming | Scanning |
|---|---|---|
| Purpose | Understand overall structure | Find specific information |
| When to use | Before reading questions | After identifying question keyword |
| Eye movement | Down the page, paragraph by paragraph | Rapid Z-pattern or column scan |
| What you read | Topic sentences only | Nothing — until you spot the anchor |
| Speed | 90–120 seconds per passage | 10–60 seconds per question |
| Result | Mental map of the passage | Location of the answer |
The Golden Rule of Scanning
Scanning only works if you have a clear target. Before scanning, always identify: (1) the anchor keyword, (2) possible synonyms, and (3) the type of answer expected (a name, a number, a reason, etc.).
Scanning — Visual Mind Map
VISUALISATIONAnchor Keywords — Visual Guide
KEY CONCEPTNot all keywords are equally easy to scan for. Use this colour-coded guide to choose the best anchor for each question.
Cannot be paraphrased. Stand out visually.
e.g. UNESCO, 1903, AUD 6.4 billion, IRRI
Unlikely to be replaced by a common synonym.
e.g. photosynthesis, calcification, bleaching
May be paraphrased — predict synonyms first.
e.g. increase, important, cause, result
Choosing the Right Anchor — Examples
| Question | Poor Anchor | Best Anchor | Why |
|---|---|---|---|
| In what year was the reef inscribed as a UNESCO site? | year, inscribed | UNESCO or 1981 | Acronym + specific year — cannot be paraphrased |
| How much does the reef generate annually? | generate, economy | AUD or billion | Currency symbol stands out visually |
| Who developed TCP/IP? | developed, who | TCP/IP | Alphanumeric code — unique and unscannable |
| What caused the Comet to be withdrawn? | withdrawn, caused | Comet | Proper noun (aircraft name) — exact match |
| How long can Scuba rice survive submersion? | survive, days | Scuba rice | Unique proper noun — appears only once |

5 Tips for Effective Scanning
TIPS- Tip 1: Always identify the anchor keyword BEFORE scanning. Before your eyes move to the passage, underline the most specific, scannable word in the question. The more specific and unusual the anchor, the faster you will find it.
- Tip 2: Predict synonyms before scanning. Spend 5 seconds predicting what synonym the passage might use. If the question says "increase", the passage might say "rise", "grow", or "surge". Scanning for the wrong word wastes time.
- Tip 3: Use your mental map from skimming. After skimming, you know roughly which paragraph discusses which topic. Start scanning in the right paragraph rather than from the beginning — this saves 30–60 seconds per question.
- Tip 4: Numbers and dates are the easiest anchors. Numbers (percentages, distances, years, prices) look different from regular text. Your eyes naturally jump to them. When a question asks "how many", "how much", "when", or "what year", scan for digits first.
- Tip 5: Stop and read carefully once you find the keyword. Scanning only gets you to the right location. Once you find the anchor keyword, STOP scanning and switch to close reading. Read 2–3 sentences around the keyword carefully to confirm the answer.
4 Critical Warnings
WARNINGSScanning without a clear target — just reading quickly. This is inefficient and you will miss the answer.
Identify your anchor keyword first, then move your eyes rapidly to find ONLY that word.
Warning 1: Do Not Scan Without an Anchor
Scanning without a clear target is just reading quickly — and it is inefficient. Always identify your anchor keyword before your eyes move to the passage.
Warning 2: The Answer May Use a Synonym
If you scan for "increase" and the passage uses "rise", you may miss the answer. Always predict synonyms before scanning. If your first scan finds nothing, try scanning for a synonym.
Warning 3: Do Not Read Every Word While Scanning
Scanning means your eyes move fast. If you find yourself reading every word, you have stopped scanning and started reading. Force your eyes to move faster.
Warning 4: Finding the Keyword ≠ Finding the Answer
The keyword tells you WHERE to look; you must then read carefully to find WHAT the answer is. Many students write down the keyword itself instead of the actual answer.
Key Synonym Pairs
VOCABULARYStudy these synonym pairs from the practice passages. Questions will use the right-hand word; the passage uses the left-hand word (or vice versa).
Exercise Set 1 — The Great Barrier Reef
5 QUESTIONSOpen-Answer Format
These questions use open-answer format — type your answer and click Check. Your answer must come from the passage. Maximum 3 words and/or a number.
The Great Barrier Reef, located off the northeastern coast of Australia, is the world's largest coral reef system, stretching approximately 2,300 kilometres and covering an area of around 344,400 square kilometres. It is composed of over 2,900 individual reefs and 900 islands, and is home to an extraordinary diversity of marine life, including more than 1,500 species of fish, 4,000 species of mollusc, and 240 species of birds.
The reef was inscribed as a UNESCO World Heritage Site in 1981, recognised for its outstanding universal value. It generates approximately AUD 6.4 billion annually for the Australian economy, primarily through tourism and fishing, and supports around 64,000 jobs.
Rising ocean temperatures pose the most serious threat to the reef. The reef experienced its most severe bleaching event on record in 2016, when approximately 30% of the coral died. A second major bleaching event followed in 2017, and a third in 2020.
Ocean acidification presents an additional challenge. Research published in 2021 found that coral calcification rates on the Great Barrier Reef had declined by 14% since 1990.
The Australian government has committed AUD 3 billion over ten years to the Reef 2050 Plan. However, environmental groups have argued that these measures are insufficient without more ambitious action to reduce greenhouse gas emissions.
🔍 Scanning tip: Scan for a 4-digit number starting with '2'. The number '2,300' appears in the first sentence of Paragraph 1.
🔄 Synonym pair: long ↔ stretching / extending / spanning | length ↔ distance / extent
📍 Evidence: "stretching approximately 2,300 kilometres"
⚠️ Trap: Do not confuse '2,300 kilometres' (length) with '344,400 square kilometres' (area). The question asks for length.
🔍 Scanning tip: Scan for 'UNESCO' — a capitalised acronym that cannot be paraphrased. It appears only once in the passage.
🔄 Synonym pair: inscribed ↔ designated / listed / recognised | UNESCO World Heritage Site ↔ internationally protected area
📍 Evidence: "The reef was inscribed as a UNESCO World Heritage Site in 1981"
⚠️ Trap: The question uses 'inscribed' — the passage also uses 'inscribed', so this is a direct match. If the question had said 'designated', you would need to recognise the synonym.
🔍 Scanning tip: Scan for 'AUD' — a currency symbol that stands out visually. Currency symbols and large numbers are the fastest things to scan for.
🔄 Synonym pair: generates ↔ contributes / produces / brings in | economy ↔ economic activity / financial sector
📍 Evidence: "It generates approximately AUD 6.4 billion annually for the Australian economy"
⚠️ Trap: The passage also mentions 'AUD 3 billion' (government investment in Paragraph 5). Do not confuse the two — the question asks about annual economic generation.
🔍 Scanning tip: Scan for '2016' first (the anchor year from the question), then read the surrounding sentence for the percentage figure.
🔄 Synonym pair: died ↔ was lost / perished / was destroyed | bleaching event ↔ coral whitening / thermal stress
📍 Evidence: "in 2016, when approximately 30% of the coral died"
⚠️ Trap: The passage mentions three bleaching events (2016, 2017, 2020). The question specifies '2016', so you must find the figure for that specific year only.
🔍 Scanning tip: 'Calcification' is a specialist scientific term that appears exactly once in the passage. It is the ideal anchor keyword — scan for it directly.
🔄 Synonym pair: declined ↔ decreased / fallen / reduced / dropped | calcification rates ↔ rate of coral skeleton formation
📍 Evidence: "coral calcification rates on the Great Barrier Reef had declined by 14% since 1990"
⚠️ Trap: The question asks 'by how much' — the answer is '14%' (the amount of decline), not '1990' (the starting year). Read the full sentence carefully after finding the anchor.
Exercise Set 2 — The History of Aviation
5 QUESTIONSThe history of aviation began on 17 December 1903, when Orville and Wilbur Wright achieved the first powered, sustained, and controlled aeroplane flight at Kitty Hawk, North Carolina. The flight lasted just 12 seconds and covered a distance of 36.5 metres. The brothers made four flights that day, with the longest lasting 59 seconds and covering 260 metres.
The First World War (1914–1918) accelerated the development of aviation technology dramatically. By the end of the war, aircraft could reach speeds of over 200 kilometres per hour and altitudes of more than 7,000 metres. The war produced approximately 200,000 aircraft and trained hundreds of thousands of pilots.
Commercial aviation began in earnest after the war. The world's first scheduled international passenger air service was launched on 25 August 1919, operating between London and Paris. The journey took approximately 2.5 hours and cost £21 — equivalent to around £1,000 in today's money.
The jet age began on 2 May 1952, when the de Havilland Comet became the first commercial jet airliner to enter service. A series of fatal crashes caused by metal fatigue led to the aircraft being withdrawn from service in 1954.
Today, the global aviation industry carries approximately 4.5 billion passengers per year. The Airbus A380, which entered service in 2007, is capable of carrying up to 853 passengers in an all-economy configuration.
🔍 Scanning tip: Scan for '1903' or 'Kitty Hawk' to locate Paragraph 1, then scan for a small number followed by 'seconds'.
🔄 Synonym pair: lasted ↔ took / continued for / went on for | first powered flight ↔ Wright brothers' flight
📍 Evidence: "The flight lasted just 12 seconds"
⚠️ Trap: The passage mentions '12 seconds' (first flight) AND '59 seconds' (longest flight that day). The question asks about the FIRST flight — answer is 12 seconds.
🔍 Scanning tip: Scan for 'World War' — a proper noun phrase that is easy to spot. Once in Paragraph 2, scan for a number followed by 'kilometres per hour'.
🔄 Synonym pair: maximum speed ↔ top speed / fastest speed | by the end of the First World War ↔ by 1918 / after WWI
📍 Evidence: "aircraft could reach speeds of over 200 kilometres per hour"
⚠️ Trap: The passage also mentions '7,000 metres' (altitude) in the same sentence. The question asks for SPEED, not altitude.
🔍 Scanning tip: Scan for '£' — a currency symbol that stands out visually. The pound sign appears only twice in the passage; the first occurrence gives the original price.
🔄 Synonym pair: cost ↔ price / fare / ticket price | first scheduled international ↔ first commercial international flight
📍 Evidence: "The journey took approximately 2.5 hours and cost £21"
⚠️ Trap: The passage also mentions '£1,000' (the modern equivalent). The question asks for the ORIGINAL cost — £21, not £1,000.
🔍 Scanning tip: 'Comet' is a proper noun (aircraft name) that appears in the question. Scan for 'Comet' in the passage — it appears in Paragraph 4.
🔄 Synonym pair: withdrawn from service ↔ taken out of operation / grounded / retired | caused ↔ led to / resulted in
📍 Evidence: "a series of fatal crashes caused by metal fatigue led to the aircraft being withdrawn from service"
⚠️ Trap: The question asks WHY it was withdrawn — the answer is 'metal fatigue' (the cause), not 'fatal crashes' (the event) or '1954' (the year).
🔍 Scanning tip: 'A380' is an alphanumeric code that is visually distinctive and cannot be paraphrased. Scan for 'A380' directly — it appears in the last sentence of Paragraph 5.
🔄 Synonym pair: carry ↔ accommodate / seat / hold | all-economy configuration ↔ all-economy layout / economy-only arrangement
📍 Evidence: "capable of carrying up to 853 passengers in an all-economy configuration"
⚠️ Trap: The passage also mentions '660 passengers' (Boeing 747) in the same paragraph. The question asks about the A380, not the 747.
Exercise Set 3 — Climate Change & Food Security
5 QUESTIONSGlobal food production faces an unprecedented challenge. The world's population is projected to reach approximately 9.7 billion by 2050, requiring a 50–70% increase in food production compared to 2012 levels. At the same time, climate change is expected to reduce crop yields in many of the world's most productive agricultural regions.
Rising temperatures are already affecting agricultural output. A 2019 study found that global wheat yields have declined by 5.5% per decade since 1980. Rice yields have fallen by 3.2% per decade over the same period.
Water scarcity presents an equally serious challenge. Agriculture currently accounts for approximately 70% of all freshwater withdrawals globally. The IPCC has warned that by 2050, up to 40% of the global population could be living in areas of severe water stress.
Extreme weather events are becoming more frequent. The 2010 Russian drought destroyed approximately one-third of Russia's wheat crop, causing global wheat prices to spike by 90% within months.
Adaptation strategies are being developed. The International Rice Research Institute (IRRI) has developed a flood-tolerant variety of rice called 'Scuba rice', which can survive submersion in water for up to 17 days — compared to just 3 days for conventional varieties. Investment in agricultural research reached USD 53 billion globally in 2020.
🔍 Scanning tip: Scan for '2050' to locate Paragraph 1, then scan for a percentage range. The range '50–70%' is visually distinctive.
🔄 Synonym pair: increase ↔ rise / growth / expansion | food production ↔ agricultural output / crop yields
📍 Evidence: "requiring a 50–70% increase in food production compared to 2012 levels"
⚠️ Trap: The question asks for the required INCREASE in production, not the projected population figure (9.7 billion). Both appear in the same paragraph.
🔍 Scanning tip: Scan for 'wheat' — a specific crop name that cannot be paraphrased. Once you find 'wheat', scan for a percentage figure immediately nearby.
🔄 Synonym pair: declined ↔ fallen / decreased / dropped | per decade ↔ every ten years / each decade
📍 Evidence: "global wheat yields have declined by 5.5% per decade since 1980"
⚠️ Trap: The passage also mentions rice yields declining by '3.2% per decade'. The question asks specifically about WHEAT — answer is 5.5%, not 3.2%.
🔍 Scanning tip: Scan for '70%' — a round percentage that stands out visually. Alternatively, scan for 'freshwater' — a compound word that is easy to spot.
🔄 Synonym pair: proportion ↔ share / percentage / fraction | freshwater withdrawals ↔ water use / water consumption
📍 Evidence: "Agriculture currently accounts for approximately 70% of all freshwater withdrawals globally"
⚠️ Trap: The passage also mentions '40%' (population facing water stress) in the same paragraph. The question asks about agriculture's share of freshwater use — answer is 70%.
🔍 Scanning tip: Scan for 'IRRI' — an acronym that is visually distinctive and cannot be paraphrased. Once you find 'IRRI', read the surrounding sentence to find the name of the rice variety.
🔄 Synonym pair: flood-tolerant ↔ able to survive flooding / submersion-resistant | developed ↔ created / produced / bred
📍 Evidence: "The International Rice Research Institute (IRRI) has developed a flood-tolerant variety of rice called 'Scuba rice'"
⚠️ Trap: The answer is the NAME of the variety ('Scuba rice'), not a description of it. The question asks 'what is the name of' — always answer with the exact name.
🔍 Scanning tip: After finding 'Scuba rice' in Q14, the answer to Q15 is in the same sentence. Scan for '17' — a two-digit number that appears immediately after 'up to'.
🔄 Synonym pair: survive submersion ↔ withstand flooding / tolerate being underwater | compared to ↔ unlike / in contrast to
📍 Evidence: "which can survive submersion in water for up to 17 days — compared to just 3 days for conventional varieties"
⚠️ Trap: The passage mentions TWO time figures: '17 days' (Scuba rice) and '3 days' (conventional varieties). The question asks about Scuba rice — answer is 17 days, not 3 days.
