Have I used good and well correctly?

Question

In my opinion, your book is very good. The text is extremely well written. You did well explaining the rules of grammar. I am a good reader and this book was easy to follow and understand. I especially like the practices and exercises in the textbook. I find it beneficial to be able to see how well I understand the material. The exercises have proven to be good practice for me when I am having a difficult time writing sentences. When I am studying I glance over the chapter summaries to get a good idea of the chapter topics. I have found the side notes to be very helpful as well. Thanks to your textbook, I have become a good writer and I do well in my classes.
