People often ask me whether reading the first sentence of each paragraph is a useful "trick". Is it a good idea to read the first sentence of each paragraph before you attempt any questions? Does this "trick" work for 'paragraph headings' exercises?
My simple answer is no*
I'm not a fan of "tricks" like skimming, scanning or reading first or last sentences of paragraphs. My approach is simple: read the question, underline words that you think you need to find, then read at normal speed until you find the relevant part of the passage. I have some different tips for paragraph matching questions, but my advice does not include reading the first sentence of each paragraph - that strategy is risky because it may lead you to the wrong answer.
*The only time that I would recommend reading the first sentence of each paragraph is if you're rushing to finish a 'paragraph headings' exercise in the last few minutes of your exam. It is sometimes possible to get the answer from the first sentence, so save this trick for an emergency (when time is running out).
