Can you trust your revision guides?

Jan 25, 2017

Can you trust your revision guides?An investigation has found mistakes in GCSE maths revision guides. Find out how you can avoid being caught out.

Researchers at Cardiff University worked through five different revision guides, checking that the example questions were correct. All of the books had a few errors, but one, designed for the WJEC exam board, had 90.

The books are now being corrected, but it's a reminder that revision guides, textbooks and websites aren't perfect. You can't avoid mistakes completely, but there are ways to keep them from spoiling your revision:

  • Look for a guide that is recommended by your exam board: this doesn't guarantee that there won't be mistakes, but it gives you a better chance.
  • Don't rely on just one book or website: it's much easier to spot errors if you look at more than one source.
  • If you're not sure about something or you think you've found a mistake, ask your teacher for help.

Unfortunately, mistakes aren't limited to revision guides: exams themselves sometimes contain errors, which can make questions confusing or even impossible. Find out what to do if there's a problem with your exam paper, and how to deal with other exam emergencies.
