Re-reading is not studying. Walk into your exam already knowing. Trained on your own textbook, sharpened by your cohort, ready before the exam that decides everything.
The remediation moment
Miss a hard question. See the passage. Return to the next one.
When a wrong answer reveals a specific gap, Onbridger does not just mark it wrong. It routes you to the prerequisite that broke, shows you the exact textbook passage that explains it, and brings you back to where you were.
You miss it
If the central bank raises the policy rate by 50bps, what happens to short-term bond yields?
Misconception tag: inverted rate-yield mapping
From your textbook
p. 84When the policy rate rises, bond prices fall and yields rise. The relationship is mechanical, not behavioral. A 50bps hike lifts the short end of the curve nearly one-for-one.
Quick check
A 25bps policy rate hike. What happens to 2-year yields?
Back to your original question, refreshed.
The engine
The engine moves with you, not at you.
Most tools march you through chapters in order. Onbridger reads every answer and decides where you need to be next. Four directions. The one you are in changes question by question.
Down · Remediation
When you miss a hard question.
You return to the prerequisite that broke. The passage from your textbook surfaces alongside a quick check. Once it sticks, you resume where you were.
Lateral · Interleaving
When you are at the productive edge.
Mixed practice across your syllabus. Topics rotate at the cadence that drives discrimination learning, not blocked drill. Chapters are visualization, not gates.
Up · Validation ahead
When you answer hard ones with ease.
A probe from a downstream topic appears. Pass it and you skip the grind. Fail it and nothing happens. Curiosity is never punished.
Consolidate · Recovery
When fatigue rises.
Difficulty eases and you stay with the same topic. The session never ends on a blank state. The next move is always defined.
The cohort engine
One cohort, many students, one engine.
Every student answering questions in your course sharpens the same engine. By your second exam term, the bank is calibrated by everyone who came before you. The personal loop runs from day one. The cohort loop activates as peers arrive.
Canonical concepts
Concept identity persists.
Re-extractions and new students bind to the same concept identity. No drift. Years stack on years.
Aggregated misconceptions
The cohort teaches the cohort.
When three peers get a concept wrong the same way, the engine teaches the next student differently.
Empirical calibration
Difficulty refits weekly.
Question difficulty refits to real cohort responses every week. Synthetic estimates retire as the cohort answers.

Material grounded
In your professor's own words.
Every question, every explanation, every remediation pulls from the lectures, notes, and past exams you actually uploaded. Each one cites a page.
“If the central bank raises the policy rate by 50bps while inflation expectations remain anchored, what is the expected effect on real yields?”
