# Review a set or folder

An SRS review uses due cards and your daily limits. You do not need to choose individual cards for each session.

## Before you begin

Create an [SRS set](https://docs.flashnerd.com/guide/srs/getting-started.md) with at least one linked deck. Free-account review credits also need to be available; a credit message is separate from the set's daily limit.

## Start and answer

1. Open **SRS** and open the set you want to study.
2. Tap **Start SRS Review**. To study several sets together, open their SRS folder and start its review instead.
3. Read the front of the card and try to recall the answer.
4. Tap **Show Answer**.
5. Choose a rating using the table below.
6. Repeat until the completion screen appears, or leave the session when you need to stop.

Saved answers remain recorded when you leave. A folder session uses each card's own set settings; it does not replace every set's settings with one shared configuration.

| Rating    | Use it when                              | Learning or relearning behavior                                                           |
| --------- | ---------------------------------------- | ----------------------------------------------------------------------------------------- |
| **Again** | You did not recall the answer.           | Returns to the first step.                                                                |
| **Hard**  | You recalled the answer with difficulty. | Repeats the current step; the first step may use an interval between the first two steps. |
| **Good**  | You recalled the answer normally.        | Advances a step, or graduates to Review after the last step.                              |
| **Easy**  | You recalled it very easily.             | Graduates directly to Review.                                                             |

For cards already in **Review**, the scheduler calculates the next interval from the grade and the card's memory history. Choosing **Again** can move the card into relearning. The interval shown with an answer helps you see the scheduling consequence before grading.

Do not use **Hard** to mean “I forgot.” **Again** records a failed recall; Hard is a successful answer.

## Two-button reviews

In the set's **SRS Set Settings → Review Behavior**, **Review Button Display** can use **4 Buttons** or **2 Buttons**. Two-button mode shows **Again** and **Good**. You can change this without changing the card template.

## Correct an answer or edit a card

Open the review action menu to find **SRS Card Actions**:

- **Undo Answer** restores the previous answer when undo is available. It can become unavailable after changes that invalidate that previous card state.
- **Edit Card** opens the same underlying card used in Home. Save the edit before returning to review.
- **Hide Tag** or **Show Tag** changes tag visibility for the session, subject to the set's display setting.
- **Suspend Card** and **Disable Card** change review availability. Their meanings differ; read [Card states and availability](https://docs.flashnerd.com/guide/srs/card-status.md).
- **Delete Card** removes the underlying card and related data, including its presence in the Home deck.

:::warning Deleting is not skipping
Use availability controls when you want to stop reviewing a card. **Delete Card** is permanent and affects the original deck.
:::

## Auto Advance

The set's **Review Behavior** page can reveal the answer and move on automatically. Configure **Time before showing answer**, **Time before next card**, and **If no answer is chosen, mark as:** before enabling it.

If you do not choose a grade before the timer ends, the configured automatic grade is recorded. Auto Advance is therefore an answering mode, not a way to browse cards without affecting schedules.

## When the session finishes

The completion screen reports reviewed cards, learning time, and accuracy. “Reviews completed!” means the current scheduled work is complete under the applicable limits; it does not mean every card has been learned permanently.

You can return to the set or folder. For additional unscheduled study, open the deck from **Home** and use its practice modes.

If you expected more cards, check [Daily limits](https://docs.flashnerd.com/reference/srs/daily-limits.md), [Scheduling](https://docs.flashnerd.com/reference/srs/scheduling.md), and [Troubleshooting](https://docs.flashnerd.com/help/troubleshooting.md).
