Skimming is reading quickly to get the general idea of a text, while scanning is searching quickly for one specific piece of information.
Explained simply
Flipping through a newspaper to see what today's main stories are is skimming. Looking through the cricket scorecard only to find Virat Kohli's score is scanning. Both are fast, but they look for different things.
Technically, both are rapid reading techniques in the MU syllabus. Skimming gives the gist, structure and main ideas. Scanning locates particular facts such as names, dates, figures or key words without reading the rest.
How it works
| Point | Skimming | Scanning |
|---|---|---|
| Goal | Overall idea (gist) | Specific information |
| What you read | Title, headings, first and last paragraphs, topic sentences, bold words, figures | Only the area where the target word or number appears |
| Question in mind | 'What is this about?' | 'Where is the date/name/figure?' |
| Examples | Previewing a chapter, deciding if a research paper is relevant, reading news headlines | Finding a train in a timetable, a word in a dictionary, a value in a data table, a name in a result list |
- To skim: read the title and headings, the first and last paragraphs fully, the first sentence of each other paragraph, and look at diagrams and summaries.
- To scan: fix the key word or number in mind, move your eyes quickly down the page, stop when you see it, and read only the surrounding sentence.
Quick example
Task: a 3-page article on electric vehicles. Skimming in one minute tells you: it compares battery types, discusses charging infrastructure in India, and concludes with policy suggestions. Then a question asks 'In which year does the article say the target for EV sales was set?' You scan for numbers like '20__' and find the sentence immediately.
Common mistakes
- Using the terms the other way round; remember sKIm = gist, sCAN = specific (scanning like a barcode scanner looking for one code).
- Skimming and then answering detail questions without going back to scan.
- Reading every word while 'skimming', which defeats its purpose.
How MU asks it
Typical forms: 'Differentiate between skimming and scanning with examples' (4 to 5 marks) or within 'Explain techniques to improve reading comprehension' (6 marks). Give definitions, a comparison table, the steps for each, and one real example each.
