Hi, prof. Hays

this week there were no parts of the text which were difficult to read for me. In fact, although it has been passed a long time since I finished studying, I have to say that I can still remember many things I studied at high school many years ago. I got a high school diploma for scientific studies, and I am at easy with these things we're studying here, at least for the moment. I have just got some troubles in memorizing definitions: I have never been good at learning things off by heart.

The only thing I have to complain about is the lack of a free version of the book for kindle. I uploaded the pdf into my ebook reader, of course, but it is not the same thing. I can not increase the font size, for example, and reading the book in this way is a little annoying. I often study as I go to work, because I go with public transport, and it helps me to optimize my
