Here is an informal review of the book that I have written (it is rather long, but hey, so is the book itself).
This page was created in conjunction with a reddit probability theory reading group. Most of the solutions below are by me, with other members of the readng group contributing to chapters 1-3 and 6. Many thanks to everyone who contributed. This site has a github repository and anyone is welcome to contribute. These solutions are unofficial.
