This website is a good resource and easy to navigate. The pages are informative, with many examples, and students could refer to these pages when writing on their own. The organization of the pages is always clear with subjects broken down into more easily digestible chunks of content.
I love the quizzes in particular. I had fun completing them myself, and I think students would enjoy the instant feedback.
It would be great if this website included printables with condensed information so that students could have a grammar and writing aid always available.
