Cover
Quick mode selects one question from each of nine evidence stations, covering all nine frozen objectives.

Why this mix works
Breadth first. Evidence discrimination second.
Sweep
Mastery mode selects model, measurement, and decision evidence inside every station: twenty-seven questions total.
Intersect
Mixed order removes the lesson cue, so every positive, negative, conditional, and quantitative finding must agree.
Repeat
A new seed changes selected records and answer positions while preserving each validated conclusion 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.
36 PRACTICE QUESTIONS · 2 STUDY MODES
Change the evidence. Preserve the boundary.
Each mode preserves its coverage target, then shuffles question order and all five choices without changing any validated scientific key.
Sources and limits
Official scope, original evidence practice.
The three properties and evidence topic lines and named cues come from the ADA Organic Chemistry specification ↗. The ADA does not publish line-level or cue-level quotas, so DAT TRAIN does not invent them.
Free OpenStax and Chemistry LibreTexts chapters support the bounded scientific models. DAT TRAIN questions and explanations are original, draft, uncalibrated, and not copied from the DAT.
