What is Study Stacks?
Study Stacks is a flash card app for studying any subject in your world. Teachers and admins can publish Class decks that everyone in the current world can study, and every student can build their own private My decks for whatever they're working on.
Study Stacks is an activity where each student studies at their own pace, in their own session. Cards are chosen for you based on how well you knew them last time, so the ones you keep missing come back around more often. Along the way you'll build daily study streaks and earn badges.
Study Stacks is perfect for:
- Vocabulary, spelling, and world language practice
- Reviewing before a quiz, test, or presentation
- Math facts, formulas, dates, and definitions
- Independent study time, tutoring sessions, and study clubs

Using Study Stacks
Everyone can use Study Stacks! When you open the app you'll land in the Library, where all of your decks live in one place:
- Class decks: decks published by your teachers and school admins. Everyone in your school sees the same Class decks.
- My decks: decks you made yourself. These are private to you, and they follow you into every world in your school, so a deck you build in one world is still there in another.

To Study a Deck:
- Click Study Stacks asset to open the app.
- Click a deck in the Library under Class decks or My decks. If you don’t see any available decks, it means no decks have been created yet

- Review the deck details at the top of the window where you can see the deck name, how many cards it has, and its difficulty.
- Choose a study mode:
- Flip: read the front of the card, try to remember the answer, then tap the card to flip it and rate yourself: Got it, Almost, or Missed.
- Quiz: pick the right answer from up to four multiple choice options. If you choose wrong, the correct answer is revealed so you still learn the card.
- Sprint: a 60-second timed challenge in the same multiple choice format. Answer as many cards as you can before the timer runs out!

- Your session starts and you can work through your cards.
- Review your results on the end-of-session screen, then click Study Again to pick another mode for the same deck, or return to the Library.

You don't have to finish a whole deck in one sitting. Study Stacks remembers which cards you've mastered and picks a fresh set for your next session. You can click End Session at any time to wrap up.
To Create Your Own Deck:
- Click Study Stacks asset to open the app.
- Click + Create a new deck in the Library.

- Name your deck and fill in the deck details.

- Click Next to move to the next page.
- There are 2 ways to add cards to your deck:
- Click Add Card, then fill in the front of the card (text, an image link, or both), the back of the card, and an optional hint. Repeat for each card you want to add. Use the up and down arrows on a card to change the order.

- Click Import Cards — helpful for big decks.

- Click the Copy template button and edit it in a text editor or Spreadsheet app like Excel or Google Sheets.
- Upload your csv or tsv file, or paste the list in the text box.

- Click Save. Your new deck appears under My decks, ready to study.
A deck can't be saved while it's empty or while any card is unfinished. Every card needs a back, plus either front text or a front image. Decks can hold up to 100 cards.

Edit icon to update title, subject, difficulty and add, change, reorder, or remove cards, then click Save.

Tips for Study Stacks
- Study a little every day! Short daily sessions build your streak and help cards stick better than one long cram session.
- Rate yourself honestly. Study Stacks uses your Got it / Almost / Missed ratings to decide which cards to show you next. Marking a card as "Got it" when you guessed means you'll see it less often than you should.
- Add a hint to tricky cards. A short nudge is often enough to help you recall the answer on your own.
- Use images on the front of a card. Great for maps, diagrams, artwork, lab equipment, and vocabulary in world language classes.
- Warm up with Flip, then test yourself with Quiz. Save Sprint for when you already know the deck well and want a challenge.
- Keep an eye out for badges. You'll get a notification the moment you earn one.
