Plain question-and-answer cards will take you a long way. But some material — a labeled diagram, a tricky term, a formula, a vocabulary pair — rewards a smarter card. MintDeck has four techniques that serious learners lean on: **image occlusion**, **mnemonics**, **LaTeX math**, and **reverse cards**. Here's when and how to use each.

## Image occlusion: learn diagrams the way you'll be tested
Image occlusion hides parts of a picture and asks you to recall what's underneath. It's the single best technique for anything visual — anatomy, maps, circuit diagrams, processes — because you study the *exact* picture you'll see on the test, not a paraphrase of it.
On the front, every label is masked:
Flip the card and one mask lifts, revealing just that answer — so each hidden region becomes its own card with its own schedule:
You can get occlusion cards two ways:
- **Import them from Anki.** Any image-occlusion notes in an `.apkg` come straight across — see the [Anki import guide](/blog/how-to-import-anki-decks).
- **Create them in MintDeck.** Add an image to a card, tap the image to open the occlusion editor, and draw a box over each part you want to hide. MintDeck turns every box into a card automatically.
Occlusion shines on anything with labeled parts. If you can find or draw a clean diagram, occluding its labels is faster to make — and far more effective — than typing out a dozen separate "what is X?" cards.

## Mnemonics: make the hard ones stick
When a fact just won't lodge, a mnemonic — a vivid, slightly absurd mental hook — often does the trick. MintDeck can suggest one for you. In the card editor, open the image generator and tap **Suggest mnemonic**: it reads both sides of the card and proposes a memorable visual or verbal hook connecting the prompt to the answer.
The cost depends on your device:
- On a recent iPhone or iPad with **Apple Intelligence** (iPhone 15 Pro and later, or an M-series iPad), mnemonic suggestions run **on-device and free**.
- On other devices, MintDeck falls back to the cloud for **0.5 credits** per suggestion.
Turn the suggestion into a note on the card, or use it as the prompt to generate a mnemonic image. Either way, it lives with the card for every future review.

## LaTeX: real math, not screenshots
For any STEM subject, typing formulas as plain text is a dead end. MintDeck renders **LaTeX** natively — write `\(...\)` for an inline expression or `\[...\]` for a displayed one, and it appears as crisp, properly typeset math on the card (and in Audio Study).
No image files to manage, no blurry screenshots — just write the math and it renders. It works on card faces and in notes, so a derivation can sit cleanly in the note while the card face asks the question.

## Reverse cards: drill recall both directions
A vocabulary card you only ever see "English → Spanish" trains you to *produce* Spanish but not to *recognize* it. Reverse cards fix that by showing the back first.
In the pre-session **Study Settings** sheet, flip on **Reverse front and back**:
A few things worth knowing:
- It's a **per-session** choice, not a permanent change to your cards — turn it on for a recognition drill, off for production.
- **Cloze and image-occlusion cards skip the flip** automatically (reversing them wouldn't make sense), as the toggle's caption notes.
- It pairs perfectly with vocabulary and term/definition decks.
Alternate directions across sessions. Studying a vocab deck forward one day and reversed the next forces your brain to build both the recognition and the production pathway — which is what real fluency needs.

## Putting it together
These techniques aren't mutually exclusive — a well-built deck uses several. An anatomy deck might combine **occlusion** diagrams with **mnemonics** for the tricky names. A language deck pairs **reverse cards** with audio. A physics deck leans on **LaTeX**. Pick the technique that matches the material, and let MintDeck's spaced-repetition engine handle the timing.
