Bloom's taxonomy
Bloom's taxonomy is a ladder of six thinking levels that go from simple to hard: remember, understand, apply, analyze, evaluate, and create. It helps you see whether a question wants you to recall a fact or actually work with the idea.
The bottom of the ladder is the easy stuff. Remember means knowing a fact. Understand means you can explain it in your own words. Those two get you partway, but most exams want more.
The top rungs are where real thinking happens. Apply means using an idea on a new problem. Analyze means breaking it apart to see how it works. Evaluate means judging what's good or weak. Create means building something new from the pieces. The higher you go, the harder it is, and the more points it's usually worth.
Knowing the ladder helps you study smarter. If a test asks you to compare or argue, flashcards alone won't cut it. You need to practice doing the thinking, not just remembering.
Maya is studying for biology. She can list the parts of a cell, that's the remember level. But her exam asks her to predict what happens if part of the cell stops working. That's apply and analyze, so she practices working through cases instead of just rereading her notes.
