Quick mode selects one question from each official synthesis line.
ORGANIC CHEMISTRY · MULTISTEP SYNTHESIS · MIXED PRACTICE
Retrieve two-step planning, multistep sequencing, functional-group selectivity, and feasibility audits with coverage-controlled sets drawn from sixteen original synthesis cases.
Why this mix works
Quick mode selects one question from each official synthesis line.
Objective mode selects one question for each of the twelve frozen synthesis objectives.
Mixed order removes the lesson cue, so continuity, atoms, compatibility, and workups must all be recovered.
A new seed changes selected cases and answer positions while preserving each route key and coverage target.
Balanced synthesis retrieval
Both modes give immediate explanations and private issue reporting. Results remain on this device and do not estimate a DAT score.
Each mode preserves its coverage target, then shuffles question order and all five choices without changing any validated route key.
Sources and limits
The four multistep synthesis topic lines come from the ADA Organic Chemistry specification ↗. The ADA does not publish line-level quotas, so DAT TRAIN does not invent them.
Free OpenStax chapters support the bounded reaction rules. Questions are original, draft, uncalibrated, and do not replace the completion form.
