I do have IEW, which I have my son use to help him complete writing assignments and research reports. Perhaps I should use it for myself as well. It’s hard to write well, or to adequately correct my son’s grammar usage when my usage is so terrible. So, I think I need to focus on grammar first. Another website that I like to visit from time-to-time, classical-homeschooling.org, has also recommended Simply Grammar. They recommend using it with the Book of Diagrams. I am glad to hear that Simply Grammar has been a great help to you. I will plan to go through these two resources along with my son. Thank you so much for your advice.
