“The tutor asked what I thought the error meant before saying anything. Annoying on day one; by week three I was doing it unasked.”

“I finished with a repository I could show in interviews. Two interviewers asked about the project before they asked about anything else on my résumé, and one of them had read the tests. I had spent eight years in retail management, and this was the first thing I had ever built that a stranger could download, install and run on their own machine.”

“The exercises break things on purpose. Fixing the failing run in module three taught me more than any of the lectures I have sat through.”

“Too basic for me. The last module is what I came for, and it is short.”

“Tomás reviews the project the way a senior colleague would: short comments, each pointing at one line of your code and asking why it is there.”
