Theory
Six verbs, not a ladder you finish.
Bloom named six things you can ask a mind to do. It is not a badge.

People treat Bloom's taxonomy like a staircase. Climb it once. Graduate. Done.
That is not how work works. You remember on Tuesday. You create on Thursday. You remember again on Friday.
The list is useful because it is honest. There are six verbs:
1. Remember
Can you bring it back? A word. A fact. A step.
2. Understand
Can you say it in your own mouth? Not copy it.
3. Apply
Can you use it on a new page, a new problem, a new shift?
4. Analyze
Can you take it apart and see the joints?
5. Evaluate
Can you judge it? Keep it, throw it out, or wait.
6. Create
Can you make the next thing with it?
Most quizzes live in Remember. They are cheap to write. They feel like progress. They rarely are.
A good tool asks more. Apply this in a new text. Analyze why that sentence failed. Create a sentence of your own.
Language needs all six. So does math. So does statistics. So does writing. So does logical thinking.
So does a checklist in a cockpit.
If a feature only asks you to remember, it has to earn its place.
The other half is difficulty. The verb is not enough. The size of the step has to be right.
