I’ll be honest with you: I spent way too long convincing myself I wasn’t ready yet. There was always one more service to review, one more practice test to run through. Eventually I stopped waiting and just booked the exam. And I passed. So if you’re reading this in a similar state of „almost ready” – this one’s for you.
The AWS Certified Developer Associate DVA-C02 is an Amazon Web Services certification exam at the Associate level, designed for developers who build, deploy, and debug applications on AWS. It consists of 65 scenario-based questions, lasts 130 minutes, and requires a minimum score of 720 out of 1000 to pass (source: official AWS Certified Developer Associate DVA-C02 Exam Guide).
Here’s everything I wish I’d known before sitting the exam.

What is the DVA-C02 exam and what changed?
The AWS Certified Developer Associate certification is aimed at developers who build, deploy, and debug cloud-based applications on AWS. The DVA-C02 version replaced the older DVA-C01 in early 2023. The key changes worth knowing about:
- Refactoring questions were completely removed
- New emphasis on optimization scenarios — you’re asked to pick the most efficient AWS-based solution, not just the correct one
- Several new AWS services added to the scope
- Security now makes up 26% of the total exam content (source: official AWS DVA-C02 Exam Guide)
The passing score is 720 out of 1000 (source: official AWS DVA-C02 Exam Guide). The score is weighted based on question difficulty — a harder set of questions effectively lowers the raw threshold you need to hit. The certificate is valid for 3 years, after which recertification requires retaking the current version of the exam.
AWS Certified Developer Associate DVA-C02 exam experience & study materials – what I actually used
AWS Skill Builder — the foundation
Before diving into practice tests, I needed a solid base. AWS Skill Builder (part of the AWS Partner Network) gave me exactly that. The material is actively maintained, and as FireUp employees we have free access through APN.
One underrated tip: set up your Skill Builder account and subscribe to updates. I caught two live Twitch sessions where Amazon employees walked through actual exam-style questions in real time. That kind of content doesn’t get advertised loudly, you find it if you’re on the mailing list.
Tutorials Dojo – the closest thing to the real exam
If I had to pick one resource that made the difference, it’s Tutorials Dojo. Based on my own experience sitting the exam in 2025, I estimate around 80% of questions I saw were identical or very close to what I’d practiced there, that’s my first-hand estimate, not a marketing claim.
But here’s the key thing: don’t memorize the answers. Many DVA-C02 questions have multiple plausible options your job is to identify the most optimal one given the scenario. Sometimes none of the answers is perfect; you’re just picking the best of what’s available. That mindset shift matters more than knowing the right answer to any single question.
Stephane Maarek’s Udemy Course – solid but proceed with caution
Stephane Maarek’s course is the most popular AWS certification resource for a reason it’s thorough, well-structured, and covers the right services in enough depth. I’d suggest starting with it, not finishing with it.
One warning: the end-of-section quizzes are significantly harder than the actual DVA-C02 exam. I nearly talked myself out of booking after a rough session with one of them. Those questions had minimal overlap with what appeared on the real exam. Don’t let a bad quiz score shake your confidence 👉 use it to identify gaps, then go book the exam.
The hardest domain: security and identity
If I had to name the section that cost me the most prep time, it was authentication and authorization — IAM, roles, SAML, Cognito, and the various ways AWS handles identity management. This domain accounts for 26% of the DVA-C02 exam (source: official AWS DVA-C02 Exam Guide) and requires not just knowing what each service does, but understanding when to use each one and what their limitations are.
The challenge isn’t just knowing what each service does. It’s understanding when to use each one, what the constraints are, and how they compare in specific scenarios. IAM roles vs. access keys. SAML federation vs. Cognito user pools. These distinctions show up constantly, often as subtle differences between two otherwise reasonable answers.
My advice: don’t just read the service descriptions. Work through scenario-based questions on this topic specifically, and understand the reasoning behind each answer.
How to register for the DVA-C02 exam
You book through the AWS Certification portal. Two options are available:
| Option | Advantages | Watch Out For |
|---|---|---|
| Testing center (Pearson VUE) | Equipment provided, controlled environment | Travel required – availability varies by country |
| Online proctored exam | Take from home, slots available next-day including weekends | Laggy software, strict room requirements |
Taking the exam remotely – what nobody warns you about
This is the section I most wish had existed before I sat down for my exam. Everyone covers study materials. Almost nobody covers what the remote DVA-C02 exam experience is actually like.
Preparing your space
The requirements are stricter than you might expect. Before your online DVA-C02 exam, make sure:
- You are completely alone in the room for the entire duration of the exam
- No materials are visible – including water bottles with labels, which can be flagged as potential cheat sheets; use a plain glass instead
- Your ID is ready – the proctor will ask to see it before the exam starts
- The room is quiet – background noise can be grounds for exam invalidation
- You know the room scan procedure – the proctor will ask you to walk around with your laptop showing the space; do a trial run beforehand
The exam software – prepare for frustration
The DVA-C02 proctoring software runs very slowly. On my Mac (Apple Silicon), clicking an answer option took several seconds to register. If you accidentally click outside the question area, the selected option can deselect – even on radio buttons.
Specific issues I experienced during my 2025 exam sitting:
- Navigating to the next question took 5–10 seconds each time
- The proctor chat appeared when the app lagged heavily, but I couldn’t type in it — the input field lost focus immediately every time I clicked
- The post-exam survey is nominally a few minutes long but practically impossible to complete due to the lag
🚀 My advice: click slowly and deliberately. Budget your time knowing that navigation itself will eat into it – this is not a fast-paced interface.
Communicating with the proctor
The session is conducted in English. In my case, the proctor’s accent was quite strong and I found it difficult to understand some instructions. If that’s a concern for you, it might be worth watching a video or two of remote AWS exam check-in processes just to know what the typical instructions look like in advance.
Results and what comes next
My results arrived by email in under an hour after finishing. They’re also available in the AWS Certification portal, where you can download your certificate and digital badge.
The certificate is valid for 3 years. Your numeric score does not appear on the certificate — only pass/fail status is shown publicly.
Honest Advice: When Are You Actually Ready?
Looking back, I was probably ready to sit the exam earlier than I did. I kept finding reasons to wait.
The readiness benchmark for DVA-C02: if you’re consistently scoring 75–80% on Tutorials Dojo practice exams and you understand why the correct answers are correct — you’re ready. Don’t wait for 100% confidence. It won’t come.
The exam is challenging but fair. The knowledge you build along the way has real practical value — I found myself applying it at work almost immediately after passing.
🚀 Good luck!
