Each form includes its selected set’s three complete original passages and all 16 + 18 + 16 questions. The four sets share no passages or questions.
READING COMPREHENSION · COMPLETE-SECTION PRACTICE
Three passages.
One section clock.
Choose from four distinct sets: twelve original passages and 200 questions. Each attempt contains fifty questions in three intact scientific-passage blocks. Timed and untimed conditions preserve exact passage membership, delay every explanation until submission, and keep a recoverable record on this device.

COMPLETE READING PRACTICE
Read and answer first. Inspect the proof later.
No correctness, rationale, or evidence span appears during the form. Navigate all fifty questions, mark items, eliminate choices, review by passage, and use delayed evidence review plus privacy-minimal raw export after submission.
READY WHEN YOU ARE
Open the 50-question form setup.
The question bank and practice controls load only when you open the form. Opening setup does not start the timer or replace saved device-local progress.
PASSAGE-AWARE ASSEMBLY
Shuffle the route.
Never sever the context.
Block
The three passage sets may change order, and questions may change order inside a set, but no question moves beside another passage.
Recover
Passage order, question order, answer order, selections, marks, eliminations, navigation, and timing state are fingerprinted for exact seven-day recovery.
Delay
Keys, explanations, option analyses, and exact passage quotations remain hidden until submission or timed expiration.
PASSAGE INVENTORY
Twelve distinct scientific contexts.
Four sets of three passages each. Counts describe original practice construction, not an official passage allocation. Each passage remains bound to stable paragraph anchors, scientific claims, sources, and question evidence.

ORIGINAL PRACTICE · HUMAN EVIDENCE OPEN
Practice is available. A score claim is not.
The 2026 DAT Candidate Guide ↗ and DAT User’s Manual ↗ control the section length and broad passage description. DAT TRAIN’s original passages and questions do not reproduce live or remembered test material.
Rights review, scientific review, passage editorial review, assessment review, representative-device accessibility evidence, and student pilot calibration still require real independent work. Every result therefore remains raw and uncalibrated.
