The majority of our grammar skills come to us when we are in grade school (or grammar school). In high school, we don't really get grammar lessons, as the curriculum is centered around writing five-paragraph essays and answering questions that prove we read a book.
After high school, our grammar skills fall dramatically. Everything we learned at a young age falls by the wayside as we succumb to the grammar social media allows... which is pretty much anything. There aren't a lot of grammar nerds left to call out poor grammar skills anymore, as we are now called "trolls" for trying to teach people the difference between "your" and "you're." The bite back on those who attempt to teach people the fundamentals of the English language on social media has led to the grammar police throwing up their hands and saying: "Okay, be wrong, but don't get mad when people don't understand you."
If you miss the good old days of people at least ATTEMPTING to form a complete sentence that has things like punctuation and subject-verb agreement, you should know that you're not alone. However, the question is: can you walk with the big dogs in the grammar circuit? Take this quiz and find out if you have better grammar skills than a 5th grader.
