These days, we all have auto-correct on our phones and spell-check on our PCs, so you can easily get away with less than perfect spelling.
Once you've left those school gates behind for the very last time, you no longer have to worry about your English teacher circling all your mistakes with bright red marker pen.
Well, until now. Because it's time to go back to school!
This quick spelling test includes some of the most commonly misspelt words in the English language and it's proving a little bit tricky.
According to the woman who created the quiz, out of 92 people she asked to complete it, only 6 people got every single one right - that's just 7%.
So are you in that top 7%? Take the test below to see if you go straight to the top of the class, or whether you need to see the teacher.
