# Reviewing your cards

> Review the cards that are due, grade your recall, cram before an exam, and see why nothing is due.

WorkRoad schedules every card for the moment you are about to forget it. Review a little every day and the cards you know well come back less and less often.

## Review what's due

### Open Review

Open [Review](https://workroad.app/review) from Activities. It shows how many cards are due now and later today. Narrow it to a **Subject** or **Study set** if you like, and pick how many **Cards this round**.

### Recall, then reveal

Choose **Start review**. Try to recall the answer, then choose **Reveal answer**.

### Grade yourself honestly

- **Again**: you didn't remember it.
- **Hard**: you remembered it with difficulty.
- **Good**: you remembered it without much effort.
- **Easy**: the answer was immediate.

On a keyboard, <kbd>1</kbd> to <kbd>4</kbd> grade and <kbd>Z</kbd> undoes the last answer.

When the round ends, **Start another round** or come back later. Answers you give offline are kept on the device and sync when you're back online.

## Cram before an exam

**Start cram** walks your cards without changing their schedule. It ignores the daily limits and doesn't count toward your daily goal, so you can go over everything the night before.

## Why nothing is due

- Nothing is due yet: Review says when the next cards come back.
- The **Subject** or **Study set** filter is too narrow.
- You reached today's limit of new cards or reviews. Review shows what's left today.
- The cards are suspended, or the set is archived.

## Hard cards

A card you keep forgetting is flagged as a hard card. [Hard cards](https://workroad.app/review/hard-cards) lists them, so you can **Edit this term** to make it clearer, or **Suspend** it for a while.

## Study settings

**Study settings** on the Review page opens [Settings → Study preferences](https://workroad.app/user/review), where you set how many new cards and reviews you get each day, your daily goal, and how hard cards are handled.

**Details: every review setting**

- **New cards per day** and **Mature reviews per day** apply to every study mode except cram. Leave reviews blank for no limit. **Subject overrides** can lower them for one subject.
- **Desired retention** is the share of cards you aim to remember when they come back, 0.90 by default. Higher retention schedules more reviews. A change applies from your next answer and leaves existing due dates in place.
- **Daily goal** counts **Scheduled answers** or **Active minutes**, up to your **Daily target**. The study day starts at 4am in your time zone.
- **Hard cards**: **Flag after this many lapses**, and **Suspend automatically when flagged**.
- **Fit FSRS to your reviews**: **Optimize parameters** tunes the scheduler to your own history once you have 500 or more usable reviews. **Use default parameters** goes back.

## A card's progress

The **Progression** action on a card shows where it stands in each activity: its stage (New, Learning, Review or Relearning), when it's due, and how difficult and stable it is. **Suspend** pauses it, and **Forget** sends it back to New for that activity.

## How scheduling works

Every study format feeds the same spaced-repetition schedule, FSRS (Free Spaced Repetition Scheduler), an open algorithm by [Open Spaced Repetition](https://github.com/open-spaced-repetition). WorkRoad runs it through the MIT-licensed [ts-fsrs](https://github.com/open-spaced-repetition/ts-fsrs) library. Its licence notice is in [THIRD_PARTY_NOTICES.txt](https://workroad.app/THIRD_PARTY_NOTICES.txt).
