I've been doing self-studying for the past few years and there's no way I could possibly truly learn the bulk of CS in only nine months. Every skill needs many hours of practice and the brain needs time to process information. Unless you're part of the 1% of people who are extremely quick learners and have profound memory retention skills, most people need a lot of time to comprehend complex topics. It's not pure coincidence that some of the best performers of a lot of subjects started when they were young: by the time they were in college/adulthood they already had thousands of hours of practice.
Also notable that the CS block is last, right before interviews. It would have made more sense if you put that first and then refereed to that knowledge in the other parts, but now it looks like Lambda school just treats CS fundamentals as interview prep instead of necessary building blocks.
Generally you need about ten years to mastery for about everything. But we're not talking about mastery. Nine months until you start being useful seems reasonable.
