Diagnostic
A calibrated baseline test, taken solo, that maps exactly where you stand across data ingestion and transformation, data store management, and data operations and support before you study anything.
About the DEA-C01 exam
The AWS Certified Data Engineer - Associate (DEA-C01) exam validates the skills to build and run data pipelines on AWS: ingesting streaming and batch data, transforming it with services such as AWS Glue, Amazon EMR and Lambda, choosing and managing data stores, orchestrating and monitoring pipelines, and applying data security and governance. AWS recommends 2–3 years of data engineering or data architecture experience plus 1–2 years of hands-on AWS work. The exam has 65 questions (50 scored, 15 unscored) in 130 minutes, with a scaled passing score of 720. DEA-C01 is the current version, governed by exam guide v1.1 (December 12, 2025), and no DEA-C02 has been announced. Data ingestion and transformation is the largest domain at 34%. Edureify's plan budgets roughly 55–70 hours of study.
The Edureify Readiness System
Edureify runs on one loop: a Diagnostic maps exactly where you stand across data ingestion and transformation, data store management, and data operations and support before you study anything, an adaptive Roadmap turns that into a day-by-day plan weighted toward your actual gaps, a self-paced Practice Loop of questions, mock exams, and spaced review builds mastery topic by topic, and an Intervention layer steps in the moment your progress stalls. Every session feeds back into a live Readiness Score that predicts when you'll be exam-ready and names the specific topics still holding you back — not a completion percentage frozen at the end of a course.
Adaptive roadmap
A day-by-day plan built from your diagnostic and rebuilt automatically as you progress — weighted toward your actual gaps, not a generic syllabus.
Practice loop
Practice questions, mock exams, and spaced-repetition review, self-paced, with mastery tracked across data ingestion and transformation, data store management, and data operations and support.
Readiness prediction
A live score with a predicted ready-by date and the specific topics still dragging it down, recalculated after every session.
Certifying a team for DEA-C01, not just yourself?
Edureify also runs as a team platform for L&D leaders: every team member gets the same self-paced diagnostic-to-readiness loop, and managers get a live dashboard showing each person's Readiness Score, predicted ready-by date, and what's specifically holding them back — plus a portfolio view for reporting on DEA-C01 readiness across the whole team.
How Tutorials Dojo approaches DEA-C01 prep
Tutorials Dojo's "AWS Certified Data Engineer Associate Practice Exam 2026" is priced at $14.99 with one year of access. It offers Timed, Review and Section-Based modes, a randomized Final Test from the full bank, detailed explanations and bonus flashcards, which is a lot of DEA-C01 practice for the price.
Tutorials Dojo presents its randomized Final Test as a final readiness check, and reports break scores out by knowledge area. There's no baseline diagnostic, adaptive daily plan or predicted ready-by date, so if your attempts show a weak spot in data store management, deciding how to fix it is up to you.
Edureify begins by testing data ingestion and transformation, data store management, and data operations and support, schedules practice toward your lowest scores, and keeps a Readiness Score and ready-by date current.

Questions people ask before choosing
Does Tutorials Dojo show my weak DEA-C01 domains?
Yes, its test reports break scores down by knowledge area. It doesn't then build a daily plan or predict a ready-by date from them.
What is Tutorials Dojo's refund policy for DEA-C01 practice exams?
Full refund within 15 days if you've attempted 2 or fewer tests, 50% if more than 2 but fewer than 5, and no refund after 5 attempts, per its FAQ.
Is a year of access long enough for DEA-C01 with either option?
Both Tutorials Dojo and Edureify give a year, and Edureify's plan budgets roughly 55–70 hours of study, so a year is ample for most people.
Edureify vs Tutorials Dojo: which is right for you?
Tutorials Dojo is a great value if you already know the AWS data stack and want plenty of explained DEA-C01 practice to sharpen up.
Edureify is the better route if you'd like to start from a measured baseline, follow a plan aimed at your weakest data domains, and see when you'll be ready.
Good practice questions help most when you know which ones to spend your time on, and that's the gap Edureify fills.
