You Scored an B
You got 8/10 questions correct.
Okay, so your grammar isn’t perfect, but it’s at least passable.
You probably know English and its rules well. You just are careless about applying them.
Proofread your writing a little more carefully. Your mistakes aren’t tragic, and they’re easy to fix.
Give grammar a little more effort, and you’ll keep your friends from shaking their heads over your blunders.
And that’s why I didn’t become an English major, folks. Okay, it was because I procrastinate too damn much for the major papers/essays such a program would actually need from me, but y’know.
PS: Stolen without shame from almadefortitude. Because, you know, credit where credit is due and all that.
