This was a mock Emily presented 3 weeks prior to her successful pass of the CTA review board in 2022.
Em said: "Of all the mocks I did, this is the one I was most pleased with my performance in, although I still did not nail everything in the scenario! This is a good scenario that is not far off the real deal in terms of size, scope and complexity."
The CTA Gang of Four website has the scenario available at the link to download if you want to solve it yourself. https://ctagof.com/wp-content/uploads...
