Study Tips

Effective use of Species depends as much on your study habits as on the algorithm itself. The following recommendations are drawn from research on memory and from the practices of successful long-term users.

Build a Daily Habit

Spaced repetition works best with consistent, daily sessions. The algorithm schedules reviews based on the assumption that you will study each day. Missing days causes reviews to accumulate, which makes the next session longer and more difficult.

Practical suggestions:

Choose a specific time each day for study. Morning sessions benefit from a fresh mind; evening sessions can serve as a review before sleep, which research associates with improved consolidation.
Shorter, more frequent and focused sessions produce better retention than infrequent marathon sessions.
If you are short on time, prioritize your review queue over new cards. Reviewing due cards maintains your existing knowledge; new cards can wait.

Rate Yourself Honestly

The scheduling algorithm relies entirely on your self-assessment. Inaccurate ratings lead to a poorly calibrated schedule.

Press "Again" whenever you could not recall the answer or got it wrong. There is no penalty for admitting you forgot — the system simply adjusts.
Press "Hard" when you recalled the answer but it required significant effort or you were uncertain.
Press "Good" when you recalled the answer correctly with normal effort. This should be your most common rating.
Press "Easy" only when the answer came to mind immediately and without any hesitation. Overusing "Easy" pushes intervals out too far, increasing the likelihood of forgetting.

If you find yourself pressing "Good" or "Easy" on cards you do not genuinely remember, your retention rate will suffer and you will need to relearn those cards later.

Strategies for Difficult Cards

Some cards are inherently more challenging. If you notice the same cards lapsing repeatedly:

Focus on distinguishing features. For species identification, pay attention to the specific traits that separate similar-looking species: distinguishing markings, size, etc.
Use the additional data fields. Each card includes taxonomic and ecological information beyond the image. Reviewing this information can create stronger associations.
Compare similar species. When two species are easily confused, study them together and note the specific differences.
Reduce your new card rate temporarily. If difficult cards are consuming too much of your session, pause new cards for a few days and focus on solidifying your existing knowledge.

Avoid Burnout

Long-term consistency matters more than short-term intensity.

Do not increase new cards too aggressively. A gradual increase of 5 cards per day is more sustainable than doubling your load.
Take the long view. Spaced repetition is a months-to-years strategy. Progress may feel slow in the first few weeks, but compound growth becomes visible over time.
Reduce your load if sessions feel like a chore. It is better to study 10 cards per day for a year than 50 cards per day for two weeks before quitting.
Celebrate milestones. Use the achievements and streak tracking to recognize your progress.

Combine Flashcards with Tests

Species offers both flashcard review and structured tests. Using both modes strengthens your knowledge in different ways:

Flashcard review builds and maintains long-term recall through spaced repetition. It is the foundation of your study routine.
Tests challenge your knowledge in varied formats, such as multiple choice, true/false, image selection, attribute association, geographic knowledge and more. They reveal gaps that flashcard review alone may not expose.
