Cover
Quick mode selects one question from each of the ten bounded reaction-family clusters.

Why this mix works
Breadth first. Full mapping second.
Sweep
Mastery mode selects one question for each of the three One-Step objectives inside every cluster: thirty questions total.
Discriminate
Mixed order removes the lesson cue, so substrate, reagents, conditions, product, and selectivity must identify the rule.
Repeat
A new seed changes selected questions and answer positions while preserving every validated reaction and coverage target.
Balanced mixed retrieval
Choose breadth or mastery.
Both modes give immediate explanations and private issue reporting. Results remain on this device and do not estimate a DAT score.
40 PRACTICE QUESTIONS · 2 STUDY MODES
Change the family. Preserve the mapping.
Each mode preserves its coverage target, then shuffles question order and all five choices without changing any validated reaction key.
Sources and limits
Official scope, original practice.
The One-Step topic and named reaction cues come from the ADA Organic Chemistry specification ↗. The ADA does not publish cue-level quotas, so DAT TRAIN does not invent them.
Free OpenStax reaction chapters support each mapping. DAT TRAIN questions and explanations are original, draft, uncalibrated, and not copied from the DAT.
