You can't use a strategy until you know the rules of the game. And several of the rules people carry into this exam come from somewhere else: a university exam with negative marking, a practice site with its own scoring, or a forum post from an older exam version. This lesson replaces those with what AWS actually publishes, and it quotes every rule.
From the SAA-C03 exam guide, verified 2026-09-25:
"There are two types of questions on the exam:
- Multiple choice: Has one correct response and three incorrect responses (distractors)
- Multiple response: Has two or more correct responses out of five or more response options"
"Select one or more responses that best complete the statement or answer the question. Distractors, or incorrect answers, are response options that a candidate with incomplete knowledge or skill might choose. Distractors are generally plausible responses that match the content area."
The exam page on aws.amazon.com says the same thing more briefly: "65 questions; either multiple choice or multiple response" (exam page).
What that means structurally:
| Multiple choice | Multiple response | |
|---|---|---|
| Options | 4 | 5 or more |
| Correct | exactly 1 | 2 or more |
| Distractors | 3 | the rest |
⚠️ Two things the fetched pages do not say:
Method: a multiple-response question is really several true/false judgements sharing one stem. Judge each option on its own against the stem. Don't choose "the best pair". Choose every option that independently satisfies the requirement.
From the guide:
"Unanswered questions are scored as incorrect; there is no penalty for guessing. The exam includes 50 questions that affect your score."
"The exam includes 15 unscored questions that do not affect your score. AWS collects information about performance on these unscored questions to evaluate these questions for future use as scored questions. These unscored questions are not identified on the exam."
50 scored plus 15 unscored is 65, which matches the exam page's "65 questions".
Where unscored items come from, per the general-information policy: "every question is first administered in beta as an unscored question on an exam. Every test form includes a small subset of these questions so that AWS can evaluate how these questions perform when actual candidates answer them."
Method: behave as though all 65 count. You can't tell which 15 don't. A question that feels oddly worded or unusually hard might be an unscored item under evaluation. It might also be a scored question you find hard. Guessing which it is wastes time and gains nothing. The practical upside: if one question throws you completely, there's some chance it doesn't count. That's a reason to stay calm, not a reason to skip it.
The guide says it (quoted above), and so does the during-testing policy: "There are no penalties for incorrect responses. Unanswered questions will be marked as wrong."
Method: that settles one decision permanently. Never leave a question blank. A blind guess on a four-option question has a one-in-four chance. A blank has none. Eliminate one option and a guess is one in three. Eliminate two and it's a coin flip. Elimination, lesson 3's subject, pays off even when you can't find the right answer, because it raises the odds of the guess.
From the guide:
"The AWS Certified Solutions Architect - Associate (SAA-C03) exam has a pass or fail designation. The exam is scored against a minimum standard established by AWS professionals who follow certification industry best practices and guidelines."
"Your results for the exam are reported as a scaled score of 100–1,000. The minimum passing score is 720. … Scaled scoring models help equate scores across multiple exam forms that might have slightly different difficulty levels."
"The exam uses a compensatory scoring model, which means that you do not need to achieve a passing score in each section. You need to pass only the overall exam."
The after-testing policy explains the scale:
"Scores for the AWS Certification exams are reported as scaled scores, rather than the raw number of questions scored correct. … As the separate exam forms may vary slightly in difficulty due to the fact they consist of different questions, the forms are statistically equated to ensure all candidates are held to the same standard of competency. For example, correctly answering seven out of 10 easy questions does not indicate the same level of knowledge as correctly answering seven out of 10 difficult questions."
And the pass mark is set per level: "The passing standard is represented by a scaled score of 700 for Foundational-level exams, 720 for Associate-level exams, and 750 for Professional-level and Specialty exams." The same page says the raw passing standard is set with "the modified Angoff technique" and carried across forms by "equating".
⚠️ What this rules out: "720 means 72%." It doesn't. The score is scaled, and the raw number of correct answers needed can differ from one exam form to another. AWS doesn't publish a raw-score conversion, and this course won't guess one.
What compensatory scoring buys you: you can have a weak domain and still pass. Domain 1 is 30% and Domain 4 is 20% (guide, "of scored content"), so a weak Domain 4 can be carried by a strong Domain 1. It doesn't buy you permission to skip a domain. The guide also warns: "Use caution when you interpret section-level feedback."
This is the exam-reading fact most people don't know. From Mentions of AWS Services on the Exam:
"AWS Certification is reducing the reading load on this exam by using official short names for well-known AWS service names that contain abbreviations or parenthetical information. For example, Amazon Simple Notification Service (Amazon SNS) appears on the exam as Amazon SNS."
"The Help feature in the exam (available for every question) contains the list of the short AWS service names and their corresponding full names."
"Note: Not every abbreviation is fully spelled out on the exam or available in the Help feature. The official full name for some AWS services includes an abbreviation that is never expanded (for example, Amazon API Gateway, Amazon EMR). The exam also might contain other abbreviations that the target audience is expected to know."
The list itself is on the general-information policy page, under "AWS Service Names", verified 2026-09-25:
| Short name on the exam | Full name |
|---|---|
| AWS CDK | AWS Cloud Development Kit |
| AWS CLI | AWS Command Line Interface |
| AWS DMS | AWS Database Migration Service |
| Amazon DocumentDB | Amazon DocumentDB (with MongoDB compatibility) |
| Amazon EBS | Amazon Elastic Block Store |
| Amazon EC2 | Amazon Elastic Compute Cloud |
| Amazon ECR | Amazon Elastic Container Registry |
| Amazon ECS | Amazon Elastic Container Service |
| Amazon EFS | Amazon Elastic File System |
| Amazon EKS | Amazon Elastic Kubernetes Service |
| IAM | AWS Identity and Access Management |
| Amazon Keyspaces | Amazon Keyspaces (for Apache Cassandra) |
| AWS KMS | AWS Key Management Service |
| AWS Managed Microsoft AD | AWS Directory Service for Microsoft Active Directory |
| AWS Private CA | AWS Private Certificate Authority |
| Amazon RDS | Amazon Relational Database Service |
| Amazon S3 | Amazon Simple Storage Service |
| AWS SAM | AWS Serverless Application Model |
| AWS SCT | AWS Schema Conversion Tool |
| Amazon SES | Amazon Simple Email Service |
| Amazon SNS | Amazon Simple Notification Service |
| Amazon SQS | Amazon Simple Queue Service |
| AWS STS | AWS Security Token Service |
| Amazon VPC | Amazon Virtual Private Cloud |
The guide adds: "Any services that are on the list but that are out of scope for the exam will not appear on the exam."
Method: two consequences.
The exam page repeats this: "This exam uses short names of some AWS services. A list of short names and corresponding full names will be available through the Help button in the exam."
⚠️ The HTML exam guide does not state the exam duration. It was re-checked on 2026-09-25 and none of the guide pages fetched mention minutes. The duration comes from the exam's own page (aws.amazon.com/certification/certified-solutions-architect-associate/), fetched 2026-09-25:
"Exam duration 130 minutes" "Exam format 65 questions; either multiple choice or multiple response"
That page could change without the guide changing. Re-check it the week you book.
Arithmetic, not an AWS figure: 130 ÷ 65 = 2 minutes per question on average.
English as a second language. From the before-testing policy: "A 30-minute exam extension is available upon request to non-native English speakers when taking an exam in English. The accommodation, 'ESL +30,' only needs to be requested once, prior to registering for an exam." That makes it 160 minutes by arithmetic. You have to request it before you register.
The on-screen mechanics, from the during-testing policy:
Breaks, same page: *"Scheduled breaks are not configured for AWS Certification exams. For exams at a test center, you are permitted to take unscheduled breaks. The time for the exam will not stop during an unscheduled break."* And: "For online proctored exams, you are not permitted to stand up from or leave the view of the camera for any reason for the duration of the exam."
None of this is AWS guidance. It's a plan built on the published facts: 130 minutes, 65 questions, a flag button, a review screen, a 5-minute warning, and no penalty for guessing.
PASS 1 (~95 min) Every question, in order. Answer EVERY one — even a guess.
Over ~2.5 min on one? Pick your best remaining option, FLAG, move on.
PASS 2 (~25 min) Review screen → flagged only. Re-read the stem, not your old reasoning.
BUFFER (~10 min) Absorbs overruns. At the 5-minute warning: are all 65 answered?
Why answer before flagging: if time runs out during pass 2, a flagged question with a provisional answer still has a chance. A flagged blank is scored wrong.
Why re-read the stem rather than your reasoning: the usual reason a flagged question feels hard is that you missed a constraint. Your earlier reasoning won't show you that. The stem will.
⚠️ Changing answers. You'll find advice both ways. None of the pages fetched here says anything on it. This course's method: change an answer only when you can point to a specific word in the stem you missed the first time. "It feels wrong now" isn't enough.
One more AWS statement shapes all of this. The guide's opening: "The exam validates a candidate's ability to design solutions based on the AWS Well-Architected Framework." And the tasks it lists include "Design architectures that are secure, resilient, high-performing, and cost-optimized".
Those four adjectives are the four domain names. They're also the vocabulary the question stems use, which is lesson 2's subject.
