How long do I have access?

Forever. Both pricing tiers are one-time payments with lifetime access. This includes all current 766 lessons and any future content we add.

'Summarise this briefly' gave summaries with a median of 90.5 words; the requirement was one sentence of at most 25. What does this show?

A soft word moves the answer in a direction but does not state a requirement, Briefly did shorten the summaries, from 130 words to 90.5, but none met the requirement. The specific wording gave 20.5 words and met it 6 of 8 times.

One reply to a discount-code complaint offered to check a refund. Which change stopped this in the specific wording?

Saying what must not appear: do not promise a refund, The soft wording asked for short and polite and said nothing about refunds. The specific wording forbade a refund promise, and none of its 8 replies mentioned one.

A specific summary began 'Word count: 24' and then gave a 15-word sentence. What is the lesson?

If a limit matters, check it in code; the model's own count can be wrong, and extra lines break the shape, The model's count was wrong, and the extra line meant the reply was not one sentence alone. A check in code catches both.

How can you tell whether an instruction is specific enough?

You could write code that says whether a reply met it, If you can write the check, the requirement is stated clearly enough for the model too; if you cannot, the model is guessing what you meant.
