كل تمرين يستهدف بناءً ضيقاً: الذاكرة العاملة، الانتباه الانتقائي، السرعة.

وضع التدريب يعطي ملاحظات فورية. وضع الاختبار موقت ومقيّم.

Each exercise here is scored so you see your real progress, not vague points. Train mode gives immediate feedback. Test mode is timed and comparable to your past sessions.

Each test is constructed using Item Response Theory (IRT) and Classical Test Theory (CTT) to ensure reliable measurement of knowledge and ability across different difficulty levels.

Questions undergo rigorous review including difficulty calibration, discrimination analysis, and distractor effectiveness evaluation to maintain high assessment quality.

Training improves performance on the trained format more than on untrained ones — but the meta-skill of "try rule → test → iterate" does generalize with practice.

1. Examine differences first: Before guessing the rule, subtract consecutive terms. The difference pattern often reveals the rule.
2. Try simple rules before exotic ones: Start with addition and multiplication. Polynomial rules are rare.
3. Use elimination: Cross off what the sequence can't be. The remaining candidates usually narrow quickly.
4. Log your misses: Remembering which rule types you struggle with lets you target practice.
