Why this mix works
Coverage first. Randomness second.
Retrieve
Mastery mode selects one question from each of the 21 study objectives. Name the requested quantity before choosing a conversion.
Interleave
Mixed order removes the chapter cue, requiring you to distinguish mass, mole, entity, density, and reaction ledgers.
Repeat
Build a new set to change the questions and answer order while preserving topic coverage.
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.
28 PRACTICE QUESTIONS · 2 STUDY MODES
Mix calculations. Preserve coverage.
Each mode covers the intended topics, then shuffles question order and all five answer choices. Your answer key stays correct after every shuffle.

Official scope, original practice.
The seven topic labels come from the ADA DAT User’s Manual 2026 ↗. The ADA does not publish Stoichiometry topic quotas, so DAT TRAIN does not invent them.
The lessons use free OpenStax instruction. DAT TRAIN questions and explanations are original and are not copied from the DAT.
