The CompTIA DataAI (DY0-001) tests whether you can actually do the work -- build models, run statistical analyses, deploy ML pipelines, and apply AI to real business problems. With 90 questions in 165 minutes and 5+ years of data science experience recommended, this exam assumes you already know the fundamentals and pushes you on applied decision-making. Built for data scientists and analysts, this app pairs full-length mock exams with adaptive, confidence-based practice.
This is not a quiz bank. TechPrep is a complete exam prep platform built on cognitive science -- confidence calibration, spaced repetition, stress inoculation, and progressive difficulty that adapts as you learn. Know exactly when you are ready for exam day.

HOW IT WORKS
TechPrep measures what you actually know -- not just what you can guess. Our confidence calibration system tracks four dimensions of mastery: what you know and know well, what you know but doubt, what you get wrong but thought you knew, and what you are still learning. This precision targeting means you study what matters most.
Progressive difficulty takes you through four exam simulation levels -- Foundation, Intermediate, Advanced, and DY0-001 Simulation -- so you build real competence before exam day.
