I have never tried to compete with an 11-year-old. Maybe because I do not even know what do they learn nowadays. But this article caught my attention because of the test in English.
Especially if English is not your mother tongue would you be tempted to try a test in Grammar? I felt that way just to find out how much I still need to learn. The test is designed for schoolchildren and contains tricky spelling and grammar quiz.
Because I had a lot of fun with it I hope you will have as well. Oh, not to forget - I am very happy with my results! If you wish you can let me know about yours. It is by no means a competition. Everything in life should be fun. So enjoy it as much as I did.
