Domain mode selects one item from each of the five official domains.
ORGANIC CHEMISTRY · FIVE-DOMAIN INTEGRATED RETRIEVAL
Lose the chapter cue.
Recover the rule.
Switch among mechanisms, synthesis, acid–base chemistry, molecular evidence, and structural evaluation with coverage-controlled retrieval from every completed first-pass Organic Chemistry bank.

Why this mix works
Remove context while preserving coverage.
Sweep
Topic mode selects one item from every one of the twenty-one official topic lines.
Switch
Mixed order requires the learner to identify whether structure, state, mechanism, evidence, or route planning governs.
Repeat
New seeds vary reachable items and all five answer positions without inventing domain weights.
Integrated Organic Chemistry retrieval
Choose domain breadth or topic sweep.
Both modes are untimed, give immediate explanations, and save only privacy-minimal learning state on this device.
144 PRACTICE QUESTIONS · 2 STUDY MODES
Change the domain. Recover the governing rule.
Each untimed mode preserves official coverage, then shuffles questions and five-choice answers without changing any validated scientific key.
Sources and limits
Complete first-pass coverage, not a released form.
The five domains and twenty-one topic lines come from the ADA Organic Chemistry specification ↗. The ADA publishes one thirty-question Organic Chemistry total and no domain weights, so these retrieval modes do not claim an official distribution.
All 144 questions are original, draft, and uncalibrated. The separate completion form now provides timed and untimed completion practice, exact recovery, and raw reporting; independent expert review, representative-device evidence, and pilot calibration remain open release gates.
