This book is easy to follow in general although there are several places where the writing is hard to follow. I enjoyed the way Durrett introduced a new topic to the readers. The examples are helpful; however, some of exercises seem to be a bit more difficult than the examples provided. There are two recommendations about this book. (1) correct typos. I located more than 10-15 places to be corrected after Durrett published his corrections on his web-site. (2) discuss more about Brownian Motion. Durrett rushed through the chapter and I found it to be hard to do the exercises in that chapter.
