Review
Come back to what you’ve learned.
Seeing something once is not the same as remembering it later, explaining it clearly, or being able to use it again. Review gives learners several different ways to return to what matters.
No credit card required.

Come back to this.
Saved Review gives learners a place to deliberately keep an idea, term, question or piece of material they want to return to later — along with why they saved it and what they want to do with it.

Remember this.
Flashcards ask the learner to recall something from memory, then look again. After each card, they can mark it Confident, Unsure or Review again — so the next pass can follow what still needs another look, not a score.

Explain your thinking.
Guided Practice asks the learner to put an idea or piece of reasoning into their own words. That can reveal whether the idea really makes sense in a way simply recognising an answer may not.

Check your understanding.
Practice Test is a learning check. It gives the learner a way to see what they can do with an idea on their own — without turning review into a high-pressure exam.

Save it. Remember it. Explain it. Check it.
Different kinds of review answer different needs. The learner can choose the approach that helps with what they are trying to remember or understand right now.
Make coming back part of learning.
Keep a way to return to the idea, practise recalling it, and check whether it still makes sense.
