AWS SAA-C03 Passing Score: What You Need to Hit

The passing score for the AWS Solutions Architect Associate (SAA-C03) exam is 720 out of 1000. That's the number to remember. You don't need a perfect score, and you don't need to clear every section individually. You need 720.

Here's what that actually means for how you study.

Is 720 out of 1000 the same as 72%?

Not quite, and this is where people get tripped up. AWS uses scaled scoring, so the SAA-C03 passing score of 720 isn't simply "72% of the questions right." Each question carries a slightly different weight, and your raw result gets converted onto a 100 to 1000 scale. Two people who miss the same number of questions can land on different scaled scores depending on which ones they missed.

The practical takeaway: aim to sit comfortably above the line in practice, not right on it. If you're scoring around 80% on solid practice questions, you're in good shape for the real exam.

How many questions can you get wrong?

The SAA-C03 has 65 questions and you get 130 minutes, which works out to almost exactly two minutes each.

Here's a detail a lot of people miss: 15 of those 65 questions are unscored. AWS uses them to trial new content, and they don't count toward your result. You won't know which ones they are, so treat every question as if it matters.

That leaves 50 scored questions. Because of the scaled scoring there's no official "you can miss exactly this many," but as a rough guide, getting around 38 of the 50 scored questions right puts most people over the line. Don't plan around the bare minimum. Build a buffer.

What the passing score doesn't tell you

The number is the easy part. Hitting it is the work.

SAA-C03 is scenario-based. You read a short business situation and pick the best architecture from four options, and often two of those options are technically correct. The exam is checking whether you can spot the one that fits the situation described, the one that's cheaper, more secure, or more resilient. That judgment is what gets you to 720, not memorizing service limits.

So how you practice matters more than how much you read. Work through realistic, scenario-style questions and read the explanation for every one, including the questions you got right. That's how you train the instinct the exam rewards.

How to know you're ready

You're ready when you can read a scenario, spot the constraint that decides the answer (is it cost, latency, or durability?), and say why the other three options are wrong. Once that feels automatic, 720 takes care of itself.

The quickest way there is reps. Practice with real exam questions and see where you land. If you're clearing 80% with the reasoning to back it up, book the exam.
