Most people make Anki cards wrong. Here's the right way: card types, what makes a card work, and the most common mistakes to avoid.
One card, one fact. Every Anki card should test exactly one thing. If your card has two facts on the answer, split it into two cards. This is the minimum information principle, and it's the foundation of every other rule in this guide.
In Anki desktop, click Add in the top toolbar (or press A). This opens the card editor. Select your deck and card type from the dropdowns at the top.
The simplest card type. Question on the front, answer on the back. Creates one card per note.
Front:
What is the mechanism of action of beta-blockers?
Back:
Competitively block catecholamines at beta-adrenergic receptors → decrease heart rate and contractility
Best for: definitions, mechanisms, facts with a single correct answer.
Creates two cards from one note — front→back AND back→front. Tests recognition in both directions.
Best for: vocabulary, drug-disease pairs, term-definition where you need recall in both directions. Warning: doubles your review load — only use when bidirectional recall is actually needed.
Hides one or more words from a sentence. The most versatile card type for factual content.
Note text:
The normal resting heart rate is {{c1::60–100}} beats per minute.
Card shown:
The normal resting heart rate is [...] beats per minute.
Best for: fill-in-the-blank facts, equations, drug doses, normal values, any statement where one piece of information is being tested in context.
Hides parts of an image. Requires the Image Occlusion Enhanced add-on. Create cards by drawing rectangles over the parts of a diagram you want to test.
Best for: anatomy diagrams, biochemical pathways, labelled diagrams, circuit drawings. One of the highest-value card types for visual learners.
Each card tests exactly one fact. If your answer has two sentences, it should probably be two cards. Long answers are hard to rate — did you get it right if you remembered the first part but forgot the second?
Instead of "What is angiotensin II?", write "Angiotensin II causes vasoconstriction by acting on ___ receptors." Context-rich cloze cards are dramatically easier to recall than bare definitions because the context provides retrieval cues.
Never create a card for something you don't understand. You'll fail the card every time, get frustrated, and eventually suspend it. Use the Feynman Technique first — understand the concept, then card the facts that come from that understanding.
Add an image to the back of cards where possible. Dual coding — combining words and visuals — significantly improves retention. A screenshot of a diagram on the back of a mechanism card helps even if you're not testing the diagram itself.
If your answer is always a single word, you'll know what level of detail to recall. If some cards require one word and others require a paragraph, you'll never know how hard to try. Decide on a consistent granularity and stick to it.
Mistake 1: Copying lecture slides verbatim
Slides are not cards. Paste a slide into Anki and you get an unlearnable blob of text. Break slides down into individual atomic facts before carding them.
Mistake 2: Making too many cards
100 cards on one lecture topic sounds thorough. But 80 of those cards might be low-value detail. Better to have 20 high-quality cards that cover the core concepts than 100 cards you'll eventually suspend out of overwhelm.
Mistake 3: Forgetting to add sources or context
When you fail a card 6 months from now, you won't remember where it came from. Add a brief source note or extra field: "From lecture 3 / First Aid p.142 / Step 1 HY topic." This helps you know how much to care about a failed card.
Mistake 4: Creating cards during your first read
Read first, understand the big picture, identify what actually matters. Then go back and create cards. Cards made during a first read often capture low-value details you won't actually need.
Creating cards manually is time-consuming. The average student spends 2–3 hours making cards for a single lecture. AI generation cuts this to minutes while applying these rules automatically.
