Why this mix works
Coverage first. Model switching second.
Retrieve
Mastery mode selects one question from every study objective for a complete twenty-seven-objective sweep.
Discriminate
Mixed order removes the lesson cue: choose among conjugate stability, proton transfer, pair or radical arrows, sequence ledgers, and energy profiles.
Repeat
A new set changes selected questions and answer positions while preserving every validated key 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 state. Preserve the ledger.
Each mode preserves its coverage target, then shuffles question order and all five choices without changing the answer key.
Sources
Official scope, original practice.
The two domain labels, nine topic lines, named facets, and arrowhead note come from the ADA Organic Chemistry specification ↗. The ADA does not publish topic quotas, so DAT TRAIN does not invent them.
Free OpenStax chapters support the lessons. DAT TRAIN questions and explanations are original and are not copied from the DAT.
