Student Reviews

"The Grammar Refresher class exceeded my expectations. The lessons were well written and explored the material in more depth than had I expected. As a result, I'm able to identify sentence structures like: run-ons and sentence fragments. The best part of the course was the discussion section. The teacher responded immediately to discussion questions with thoughtful, detailed answers. She was incredible! It was extremely helpful to be able to ask her to clarify troubling areas, or explain style differences."

"I haven't taken that many on-line classes (five), but this has been, by far, the most valuable course to me, both educationally and personally. Your lessons and the added guidance have helped me to feel more confident about the grammar I use when I talk and write. Everyone in education should take this course each time they renew their certificate. I hope you are being greatly rewarded for your dedication to your job. This student very much appreciates it! Thank you!"

"One more thing I wanted to say before this forum closes: Thank you for your timely responses and down-to-earth, friendly tone in this discussion area. I suspect that you have several very large classes going on at once, and I really appreciate how you kept up with this forum. I always looked forward to reading your responses to my questions, not only because they were thoughtful and helpful, but also because they showed that you truly care about your students and their understanding of grammar. All the best to you, Ellen. I hope our paths cross again!"
