The real Natural Sciences section runs Biology, General Chemistry, and Organic Chemistry under one shared 90-minute clock with no sub-timer per subject, and PAT, Reading Comprehension, and Quantitative Reasoning are each single continuous timed sections. This portal instead lets you drill one of the six content areas at a time: pick a section below and take a focused, timed, 15-question testlet (fewer if a section's bank has fewer items), paced proportionally to the real section's minutes-per-question. It won't feel like sitting the full-length exam, but it's built for honest, untimed-then-timed review of each content area.
The real DAT converts raw scores to a 1–30 scale per section (plus Total Science and Academic Average composites) using the ADA's own proprietary conversion tables, which are not publicly reproducible. This portal cannot recreate that conversion, so testlet results here report plain accuracy (percent correct) on a fixed testlet, with a study-signal label — not a 1–30 scaled score of any kind.
