You failed. The score report says somewhere between 672–680 and passing is 720. That gap feels small but it’s not. You’re not almost there. You’re stuck in a loop where generic practice tests aren’t exposing what you actually don’t know.
Most candidates who plateau at 70% on AWS Developer Associate (DVA-C02) practice exams do the same thing three times: take a full practice test, miss 60–80 questions, feel discouraged, take another full practice test, get the same score. Nothing changes because they’re treating the exam like one monolithic thing instead of six separate domains with different difficulty levels.
You need to stop taking full-length practice exams right now.
What Your Score Actually Means
A 70% on practice test means you’re scoring roughly 672/720. The DVA-C02 exam has 160 questions, and you’re getting about 112 correct. That’s a fail by 48 points.
But here’s what matters: you didn’t miss 48 random questions across all topics. You missed clusters of questions in specific domains.
The DVA-C02 exam breaks down like this:
- Deployment (28%): CodeDeploy, CloudFormation, Elastic Beanstalk, AppConfig
- Security (26%): IAM, KMS, Secrets Manager, VPC
- Development with AWS Services (20%): Lambda, API Gateway, DynamoDB, SQS
- Refactoring (14%): Performance optimization, cost optimization
- Monitoring and Troubleshooting (12%): CloudWatch, X-Ray, logs
If you’re stuck at 70%, you’re likely scoring 50–60% in one domain and 75–85% in the others. That’s your real problem. One weak domain is dragging your overall score down.
The Real Reason You Failed AWS Developer Associate (DVA-C02)
You’re not actually weak at AWS. You’re weak at specific services and specific question types.
Here’s the pattern: candidates who get stuck at 70% on practice exams usually fall into one of three categories:
Category 1: Lambda and event-driven architecture confusion. You see a question like: “A Lambda function is triggered by an S3 event notification. The function sometimes fails silently. Where would you investigate?” You’re not sure if the answer is CloudWatch Logs, X-Ray, or the Lambda Dead Letter Queue. You guess. Half the time you’re right, half wrong. These questions drop your score 8–12 points because they’re 5–7% of the exam.
Category 2: IAM policy evaluation gaps. Questions show you a JSON policy and ask what permissions it grants or denies. You don’t have a mental model for how to read IAM policies fast. You second-guess yourself on NotResource, Condition blocks, and aws:SourceVpc. That’s another 8–10 points.
Category 3: API Gateway and CloudFormation syntax. You know what API Gateway does, but you don’t know the difference between AWS::ApiGateway::RestApi and AWS::ApiGatewayV2::Api in CloudFormation. You know CloudFormation exists but you’ve never actually read a template. These are gotchas worth 6–8 points.
Add those three together and you’re at your 70% plateau.

What To Do In The Next 48 Hours
Step 1: Download your score report. Look at your DVA-C02 practice test report and identify which domains you scored lowest in. If the report shows domain breakdowns, write down your percentage in each of the five domains. If it doesn’t, go back and manually count which questions you missed and group them by topic.
Step 2: Admit which domain is killing you. Be honest. Is it Lambda? IAM? API Gateway? Don’t pick two domains. Pick one. That’s your focus.
Step 3: Spend 4 hours on that domain alone. Not on a practice test. On targeted learning:
- If Lambda: read the AWS Lambda Developer Guide sections on concurrency, error handling, and event sources. Do 15–20 Lambda-specific practice questions.
- If IAM: work through the AWS IAM Policy Simulator on the console with real policies. Answer 20–25 IAM-specific questions.
- If API Gateway: build a test API Gateway in the console. Create a resource, method, and integration. Read one CloudFormation template that deploys API Gateway.
- If CloudFormation: read 3–4 example templates from AWS. Don’t memorize syntax. Just get familiar with structure.
Step 4: Do 30 domain-specific questions on your weak spot. Not a full practice test. Just questions on that domain. Your goal is 85%+ on those 30 questions.
Your Retake Plan
Your next full practice exam should be in 7–10 days, not tomorrow.
Days 1–3: Domain-specific drills (as above). Days 4–6: Review the AWS Developer Associate exam guide. Re-read the domains you struggled with. Do 40–50 more targeted questions. Day 7: Take one more full practice exam. If you’re at 75%+, you’re ready to schedule the real exam.
If you hit 75% on that second practice test, book the real DVA-C02 exam for 3–5 days out. Your brain will keep the information fresh.

One Thing To Do Right Now
Stop what you’re doing. Open your practice test score report. Look for the domain where you scored lowest. Write it down—just the name, Lambda or IAM or whatever it is. That’s your next 4 hours of work. Not more tests. Not YouTube. Domain-specific drills.
You’re 48 points away from passing. Those 48 points are concentrated in one area. Find it, fix it, retake.
