# Checkpoints and Flashcards

> Every LoWisa level ends with a checkpoint and a deck of flashcards on what you just learned. How they work, how to choose the number of cards, and how to use them for revision.

Finishing a lesson and remembering it next month are different things. Every level in LoWisa ends with a checkpoint and a deck of flashcards, so you test yourself while it is fresh and have something to revise with later.

## Where to find them

On the path map, each level shows its lessons followed by **Checkpoint & flashcards**. It opens when you finish the level's lessons.

## How a deck works

1. **Choose how many cards.** The deck starts with a number that covers every lesson in the level. Use fewer or more, or type your own number.
2. **Answer before you flip.** Say the answer to yourself, then tap the card to see it. Turn on Shuffle to mix the order.
3. **Mark each card.** Tap Know it or Still learning. Cards you are still learning come back in the next round until you know them.
4. **Revise later.** The deck stays on the level, ready to run again after a day and after a week. See [Active recall and flashcards](/learn/active-recall-flashcards/).

Cards test the real topics of the level, not the analogies used to explain them, so they match what an exam or an interview asks.

## On a free level

Level 0 of every course is free, including its checkpoint and flashcards. After the free deck, the app shows the plans that open the rest of the course. See [Plans and credits](/help/plans-and-credits/).
