The questions feel too difficult. What can I do?
Before starting a problem, choose “Try an easier level” in Practice. Reviewing a lower level preserves your official level. Review answers still use your daily practice allowance. Your official difficulty also adjusts from your answers.
Where are tables and mental maths?
Arithmetic tables help you explore number facts. Mental maths trains calculation speed and has its own starting diagnostic. Both are linked from Learn.
Do I have to compete?
You can focus on learning on your own. Use the Play menu when you want to explore duels, clubs, or public matches. Competitive rating is separate from your learning progress.
