What is Knowledge Health Score?

A composite readiness signal using topic accuracy, recall stability, revision timeliness, and recent mock behavior. এটি একটি readiness signal যেখানে topic accuracy, recall stability, revision timeliness এবং সাম্প্রতিক mock behavior একসাথে ধরা হয়।

Does Ogroshor replace teachers?

No. Ogroshor supports practice and feedback loops while keeping human guidance central. না। Ogroshor অনুশীলন ও ফিডব্যাক লুপে সহায়তা করে, তবে মানবিক গাইডেন্সকে কেন্দ্রেই রাখে।

The Learning Science Behind Ogroshor

Ogroshor is built on a measurable learning loop: diagnostic -> practice -> explanation -> revision -> mock -> readiness.

Why cramming fails

Cramming creates short-term familiarity but weak long-term recall. Under exam pressure, this often collapses.

How spaced repetition improves memory

Repeated retrieval at increasing intervals strengthens memory traces and reduces forgetting.

How FSRS schedules revision before forgetting

FSRS estimates memory stability and difficulty, then schedules reviews when recall probability starts to decline.

How diagnostics find weak topics

Short diagnostics map weak concepts early so learners spend time where score recovery is highest.

Why AI Tutor gives hints instead of direct answers

Guided reasoning builds transferable understanding. Direct answer dumping often blocks real learning.

How mock tests measure readiness

Readiness is not only marks; it includes timing control, error pattern, and topic stability under pressure.

AI-era learning protection

In the AI era, we protect human thinking by design: guided reasoning, retrieval practice, and transparent official-source linking.
