How to prepare for the AWS SAA-C03 exam: a study plan

By LearnSome.tech · Published 2026-11-11

TL;DR

To prepare for the AWS Certified Solutions Architect Associate exam, follow AWS Skill Builder's 4-step exam prep plan: review the exam guide, refresh your knowledge and skills, review and practise for the exam, then take the Official Practice Exam. The exam lasts 130 minutes and has 65 questions, each either multiple choice or multiple response. No exam replaces production experience, so build and break real designs in your own account while you study.

What does the SAA-C03 exam test?

SAA-C03 tests your ability to design solutions based on the AWS Well-Architected Framework, and it is meant for people who perform a solutions architect role. It also checks that you can design secure, resilient, high-performing and cost-optimised architectures, and review existing solutions to find improvements. AWS describes the certification as focused on the design of cost and performance optimised solutions. You do not need deep hands-on coding experience, although familiarity with basic programming concepts is an advantage.

The Well-Architected Framework helps you understand the pros and cons of decisions you make while building systems on AWS. By using it, you learn best practices for designing and operating reliable, secure, efficient, cost-effective and sustainable systems in the cloud. We suggest reading the framework alongside the exam guide, so every design choice you make has a reason you can explain.

What are the SAA-C03 domains and weights?

The exam has four content domains, led by Design Secure Architectures at 30% of scored content and Design Resilient Architectures at 26%. Design High-Performing Architectures carries 24% and Design Cost-Optimized Architectures carries 20%.

Task 1.2, designing secure workloads and applications, includes skills in designing VPC architectures with security groups, route tables, network ACLs and NAT gateways. In task 2.2, Design highly available and/or fault-tolerant architectures, the guide lists knowledge of disaster recovery (DR) strategies, for example backup and restore, pilot light, warm standby and active-active failover. High performance covers storage, elastic compute, databases, network architectures, and data ingestion and transformation. Task 4.2, designing cost-optimized compute, expects knowledge of purchasing options such as Spot Instances, Reserved Instances and Savings Plans.

Domain	What it asks you to design
Secure	Access, networks, data protection
Resilient	Loose coupling, high availability, recovery
High-performing	Storage, compute, databases, networks, ingestion
Cost-optimised	Storage, compute, databases, networks

We suggest spending the most hours on the heaviest domain, while still leaving real time for the lightest one.

What is the SAA-C03 exam format and pass mark?

SAA-C03 is a pass or fail exam reported as a scaled score of 100 to 1,000, and the minimum passing score is 720. Only 50 questions affect your score, while 15 unscored questions are mixed in and not identified on the exam. Unanswered questions are scored as incorrect, and there is no penalty for guessing. Scoring is compensatory, so you do not need a passing score in each section, only in the overall exam.

The exam costs 150 USD, and you can sit it at a Pearson VUE testing center or as an online proctored exam. Your certification is valid for 3 years, and passing the latest version of the exam or earning the Professional certification renews it. Our advice is to answer every question on the day rather than leave any blank.

Is SAA-C03 hard?

How hard it feels depends mostly on how much hands-on design time you have had with AWS. AWS recommends at least 1 year of hands-on experience designing cloud solutions that use AWS services. Even so, candidates with 1 to 3 years of IT experience have prepared for and earned it as a starting point on their AWS learning journey. If you have no IT work experience, AWS suggests earning the AWS Certified Cloud Practitioner first for foundational knowledge.

Wrong options are written as plausible distractors that a candidate with incomplete knowledge or skill might choose. Multiple response questions have two or more correct responses out of five or more options. In our experience, reading the requirement carefully matters as much as knowing the services.

What is the best course for the SAA-C03 exam?

The best place to start is AWS's own exam prep plan and exam guide, before you pay for any course. Step two of that plan suggests digital courses where you need to fill gaps, plus practice with AWS Builder Labs, AWS Cloud Quest and AWS Jam. In step three, you explore each domain's topics and how they align to AWS services, then find gaps with exam-style questions and flashcards. AWS also runs free, live webinars led by AWS-accredited instructors, and free Exam Readiness digital courses you can take anytime. Pick a third-party course only to fill a gap the official material leaves, and judge it by how much building it asks of you.

Read the exam guide and its domain pages first, and mark each task you cannot yet explain.
Build each pattern in your own account: a private subnet, a queue between tiers, a database standby.
Price every design you build, and note the cheaper option you turned down and why.
Sit the official practice exam last, as a readiness check rather than a study tool.

Where can you find SAA-C03 practice exams?

The official route is the AWS Certification Official Practice Question Set for exam-style questions, then the AWS Certification Official Practice Exam to assess readiness. On the real exam, short names are used for some AWS services, and a list of short and full names is available through the Help button. Practise with both names, so a short name never slows you down on the day.

The exam guide says the table of classifications gives general information that highlights your strengths and weaknesses, and to use caution when you interpret section-level feedback. Treat a practice score the same way: use it to find weak domains, not to predict your result. Review every wrong answer until you can say why each distractor fails the scenario.

The exam guide lists the weightings, content domains and task statements for the exam. It is not a complete list of exam content, but it adds context for each task statement to help you prepare.

For design practice, AWS provides the AWS Well-Architected Tool for reviewing your workloads at no charge. Well-Architected Labs gives you a repository of code and documentation for hands-on experience implementing best practices. Once you earn one AWS Certification, you get a 50% discount on your next AWS Certification exam. Use these free pages before you spend money, and come back to them in your final week.

From our labs

In our Solutions Architect course, you learn to find the requirement and the qualifier in a long scenario and strike options that break a stated constraint. A later lab has you match backup and restore, pilot light, warm standby and multi-site active/active to a workload's RTO, RPO and budget. You finish with a timed mock weighted like the real exam, read the result by domain and task statement, rank what to revisit by expected marks lost, and decide when you are ready to book the exam.
