Step-by-Step Examples

Example 1
Anki Med School

500 cards, 20 new/day, 1.5 min new, 0.5 min review, Anki.

  • New: 20 x 1.5 = 30 min
  • Reviews: 60 cards x 0.5 = 30 min
  • Daily: 60 min
  • Days to add all: 25 days
✓ 60 minutes/day Anki
Example 2
Language Vocabulary

1,000 cards, 15 new/day, 1 min new, 0.3 min review.

  • New: 15 min | Reviews: ~45 x 0.3 = 13.5 min
  • Daily: ~28.5 min
✓ ~29 minutes/day
Example 3
Cramming for Exam

200 cards, all reviewed daily.

  • Daily: 200 x 0.5 min = 100 min
  • Not sustainable; use Anki for long-term retention
✓ 100 min/day cramming

Common Mistakes to Avoid

⚠️
Adding cards faster than reviewing

Anki debt builds quickly. Adding 30 new cards/day while generating 90 reviews becomes unsustainable within weeks. Start with 10-15 new cards/day until you understand your sustainable rate.

⚠️
Postponing reviews

Postponed Anki reviews compound. Missing one day doubles the backlog. Reviews are scheduled because spaced repetition requires specific timing. Prioritize daily consistency over cramming sessions.

⚠️
Making cards too complex

The best flashcards test one fact only. Avoid: 'List all 10 cranial nerves.' Better: individual cards for each nerve. Minimum information principle: one clear question, one clear answer.

Frequently Asked Questions

What is Anki? ▾
A free, open-source spaced repetition software that schedules flashcard reviews at optimal intervals for long-term retention. Used extensively by medical students, language learners, and anyone learning large volumes of information. Available on all platforms.
What is spaced repetition? ▾
A learning method that reviews information at increasing intervals. New material: reviewed in 1 day. Known material: reviewed in 3 days, then 7, 14, 30, 90 days. This exploits the forgetting curve to maximize retention with minimum review time.
How many cards can I review per day? ▾
Sustainable rates vary by person and content difficulty. Language vocabulary: 100-200 reviews/day. Medical: 100-300 reviews/day. Starting new: 50-100 reviews/day. Using Anki, this typically takes 20-60 minutes depending on difficulty.
Pre-made vs self-made cards? ▾
Pre-made decks (Anki shared decks: medical, language, history) save time. Self-made cards have better retention because making the card is itself an encoding activity. Hybrid: use pre-made as a base, customize the cards you find difficult.
Anki vs Quizlet? ▾
Quizlet: better for collaborative studying, teacher-created sets, simpler interface. Anki: better for serious long-term retention (true spaced repetition algorithm), highly customizable, more efficient for large decks. For long-term learning, Anki is significantly more effective.
