Do you still remember what they taught you in elementary school? Geography, science, mathematics – you knew it all by heart. But now try answering questions that 9th graders commonly master. You may find that you’ve missed a lot of things!

We’re long past school, but the basic knowledge should remain. But the reality is often different – what we once learned by rote is now crowded out by daily worries, work responsibilities and the information we need in adult life. River names, chemical elements, historical dates or mathematical formulas are simply not something we use every day. And that’s why going back to the basics in school tends to be surprisingly challenging for many adults.

How is it that ninth graders can pass a test that adults falter on? The answer is simple – they have the information fresh. They are learning it now, reviewing it, and writing tests on it. We adults have had time to remember a lot of things. And honestly – when was the last time you solved how many degrees are the sum of the interior angles in a pentagon, or which gas makes up the largest part of the Earth’s atmosphere? Still, this is knowledge that forms the basis of our education and that every educated person should know.

It’s not just a matter of remembering the right answer. It’s whether you can demonstrate that basic education is meaningful and that some things just remain important no matter how many years you’ve been out of school. A quiz like this is an opportunity to see how much of your school days are still in your head – and maybe even motivate you to revise or learn something new.
