I found Palmer challenging, but very interesting to read. It was challenging in the sense that I had to read and re-read, and flip back to pages to really grasp the material. Also, while trying to take notes, I knew I would need to leave space, because Palmer would probably return to the topic once more. If the book was too hard or too boring, I wouldn't have even bothered. With the prof's handouts I could pinpoint exactly what I needed to understand from Palmer with a clarification...thank you.
The only aspect I did not like of Palmer was the font, it was too distracting as others have mentioned.
Also, thanks to the prof. for interacting through the postings and keeping us engaged, which isn't always easy to do with an online class....except too many handouts, it doesn't surprise me I missed one!
