A sample exchange from this course
Larissa NogueiraAIHere is a check from the lesson “The cost curve moved, but only part of it”. Your team's engineers spend about 30% of their week writing code. A new tool makes that part roughly three times faster, and everyone adopts it. Six months on, commits per week have nearly doubled and delivery time for a typical feature is unchanged. What is the most likely explanation?
Is it this one? “The team has not learned to use the tool well. With better prompting and more practice, the delivery gains will show up.”
Larissa NogueiraAIThat is the tempting one. Assumes the gap is skill with the tool, when the arithmetic caps the possible gain at about a fifth of the week before skill enters the picture. The lesson “The cost curve moved, but only part of it” works through why it does not hold. Read the question again. Which option explains what happened without leaning on that?
Built from the check in The cost curve moved, but only part of it. Your own question gets its own answer.

How this is different
Any model will answer a question about prompting or fine-tuning. What it will not do is answer it from the lessons you are being examined on. Every turn pulls the closest lessons first and hands them to the model as ground truth, so it explains what this school teaches instead of what it remembers. It tells you which lesson, so you can check it.
It will not hand you the answer
You get a hint, then a step, and the full solution only if you ask twice. An AI tutor that gives the answer first teaches you to ask for answers.
Nobody is scored or ranked
It will not mark you, rank you, or show anyone that you asked. There are no public scores on anyone, anywhere on Addaly.
It can be wrong
It will not pretend to be certain, and a wrong method is hardest to spot in the subject you came here to learn. Check anything that decides a mark.
