Walker is the kind of teacher who you gotta suck up to if you wanna pass. I've had her for both Yoga and English and believe me when I say that she will really help you out if your nice to her. She does however get really involved with you if you have some personal issues, and will guilt trip you about work because she's pretty insecure. As long as you get your work in, participate a few times a week in class and are nice to her, you'll do fine.
Ms. Walker rocks. I love her, she helped me to become a good writer, which I know will always help me in my life. She's awesome.
