What's new
- SM-2 algorithm for Error Deck. Fixed intervals replaced with an adaptive review system. Answer confidently — intervals grow faster. Struggling with a question — the bot shows it more often until it sticks.
- Streak reset fixed. Previously a wrong answer didn't reset the correct-answer counter, so intervals could grow incorrectly after mistakes. Now the streak resets to zero on every wrong answer.
- Blog with filters. A new Blog section launched on the site with five categories: Updates, Features, Tips, Insights, Stories.
How the system adapts
Each question gets its own review schedule based on your answers. Answer confidently — the bot shows it less and less often. Get it wrong — it comes back sooner. No fixed schedules: intervals adjust to each person individually. The system itself decides when to show a question next — there's nothing to configure manually.
For questions you know well, intervals quickly grow to weeks and months. For difficult ones, they stay short until the answer becomes automatic.
The algorithm has been battle-tested for years — millions of people use it in Anki and other learning apps. PLTest adapted it for the Telegram bot format and Polish exam preparation. This lets you focus on what truly needs attention, rather than reviewing every question from scratch.
What does this look like in practice?
Picture this: you answer a question about the Polish Constitution for the first time. Right — the bot shows it again in 6 days. Right again — 15 days. Once more — 39 days. A mistake — the count resets and it appears the next day. After 2–3 months of regular sessions, most questions shift to monthly intervals — you spend time only on what genuinely still needs attention.
