Grammar? What Grammar?

If there is one thing I want to say to every English teacher I have ever had, is that they need to focus more on English grammar. While I've been studying for this test that I have to do next week, I realized just how much I do not know about grammar. I feel stupid because i'm in college and I couldn't tell you what an Object Compliment is or what subjects are. I wish you had taught me more and that I understood it, because I honestly can say I do not. I wish I could tell them that they need to focus on grammar, because I feel so unprepared.
