I have not been verified, but I am MARSOC CSO. I know Rob Shaul and from attending his course and I've learned a lot. His "selection training programs" seem to be pretty good. He's getting good results. That being said the ten week A &S prep would probably be alright if you truly push yourself. I've read through it and I have some issues with it, but they are minor. You all know to get some good boots, thick socks, get used to having a ruck on. Also get into the pool and practice your side stroke and breast stroke. If possible tread water for 10 minutes and longer and practice cross overs. Many, many candidates show up and they are retards in the pool. Understand this, we are an amphibious branch, as a future MARSOC CSO you are expected to be comfortable in the water. Any way I'm working on getting verified, so please save the questions and re-buffs for IM's.
