It looks like Taylor Swift schooled Princeton Review as the SAT prep book the school released to aid students in the upcoming exam included an item in the standardized test that provided the incorrect words to one of the pop artist's famous songs, according to PEOPLE.

In a chapter in the said booklet, the SAT publishers shared that one of the best sources of grammatically incorrect sentences could be found in the songs of the youth's favorite music icons. The singers cited by the reviewer included Katy Perry, Lady Gaga, Whitney Houston, and Swift herself.

"Pop lyrics are a great source of bad grammar. See if you can find the error in each of the following," instructed the standardized test which went on to list down the items. Among those included in the list was a line from Swift's song, "Fifteen," which soared to the top spot in 2009.

In the example, the reviewer shared the following lyrics from the song: "Somebody tells you they love you, you got to believe 'em." The correction provided for the incorrect words was: "Somebody tells you s/he loves you, you got to believe him/her," which adheres to the rules on pronouns.

This might have been a learning experience for Swift had the correct lyrics of her song been included. Since the line was actually, "Somebody tells you they love you, you're gonna believe them," it appears that the SAT reviewer corrected an inexistent mistake after all.

With the huge following of Swift, it would have been impossible for the mistake to remain unnoticed. One of the singer's fans, who is presumably studying for the SAT exam, pointed out her disappointment over the supposed atrocious grammar of her idol. However, the other "more knowledgeable fans" of the artist quickly remarked on the inaccuracy of the lyrics and even called the attention of Swift herself.

Not one to take criticism lying down, Swift fired back at the publishers and remarked how the lyrics were incorrectly quoted. "Not the right lyrics at all pssshhhh," responded the artist in the post that quickly became viral in Tumblr.

"You had one job, test people," she added, directly addressing the creators of the now-controversial SAT reviewer. "One job," Swift reiterated, presumably in an effort to clearly point out the error.

The singer also tagged the Tumblr post with, "ACCUSE ME OF ANYTHING BUT DO NOT ATTACK MY GRAMMAR." With this warning, Swift included the lyrics of the controversial song beside it.
