Part of my Writing final the semester will be what my teacher calls a diagnostic. He gives us about 50 multiple choice questions. It'll ask us things like which sentence is most clear and concise, word word is misspelled or misused (ex/ effect vs. affect), or ask questions with comma splices or misused semi colons. We've been doing them every couple of weeks in class but I haven't been doing as well as I'd like to on them and I was hoping maybe someone knew of some good websites where I could go for more studying/practice tests. This is for a college writing class (I feel like by now I really should know this stuff but I still don't).
