This week Year 6 pupils across the country will sit down to take their Sats Tests.
The tests have been a big topic of discussion in recent weeks after thousands of parents signed a petition supporting a protest of the exams and a 'rogue marker' was said to have leaked a test the day before it was taken.
The Let Our Kids Be Kids campaign said that children are being "over-tested, over-worked and in a school system that places more importance on test results and league tables than children's happiness and joy of learning".
But even if they are challenging for children, they can't be that hard for adults... Or can they?
We've taken questions from sample Sats papers published by the Government in the years 2014, 2015 and 2016 so that you can test yourself.
