AWS certifications
3× AWS CertifiedThese are the exact notes I wrote and revised from to clear all three of my own AWS certifications — domain breakdowns, service comparisons, and the details that actually show up in the exam. Free to download as PDFs, no sign-up.
20+ students have cleared their AWS exams with these notes, and the Reddit community has been generous with its thanks.
01FoundationalCLF-C02
A practical revision companion for core cloud concepts, services, security, and billing.
Covers: Cloud concepts and the AWS global infrastructure, core services such as EC2, S3, RDS and Lambda, IAM and the shared responsibility model, pricing models, support plans and billing tools.
02ArchitectureSAA-C03
Architecture patterns and service notes gathered while preparing for the associate-level exam.
Covers: VPC and networking design, EC2 and auto scaling, S3 storage classes, RDS and DynamoDB, high availability and fault tolerance, decoupling with SQS and SNS, security, and cost optimisation.
03AI & machine learningAIF-C01
A focused set of notes for revising the foundations of AI and machine learning on AWS.
Covers: AI and machine learning fundamentals, generative AI concepts, Amazon Bedrock and SageMaker, prompt engineering, the managed AI services, and responsible AI practices.
Accessibility
Written for developers who want to build accessible products properly, not just pass an audit.
In depth read by developers who wanted accessibility implementation explained, line by line.
01Open guide
A code-first guide to WCAG, semantic HTML, ARIA, keyboard navigation, and React Native accessibility.
Covers: WCAG 2.2 and the POUR principles, semantic HTML, ARIA roles and live regions, keyboard navigation and focus management, colour contrast, React Native accessibility props, and testing with VoiceOver and TalkBack.
Questions
Yes. Every set of notes on this page is free to download as a PDF, with no sign-up, email capture, or payment. They are shared with the community exactly as they were written.
Three exams: AWS Certified Cloud Practitioner (CLF-C02), AWS Certified Solutions Architect – Associate (SAA-C03), and AWS Certified AI Practitioner (AIF-C01). Each set follows the domains in that exam's official guide.
Start with Cloud Practitioner (CLF-C02) if you are new to AWS — it establishes the vocabulary, the global infrastructure, and the billing model that every other exam assumes you already know. Move to Solutions Architect Associate (SAA-C03) once you are comfortable designing with core services. AI Practitioner (AIF-C01) is a separate foundational track for AI and machine learning on AWS.
They are written to be your revision layer, not your only resource. I used them alongside hands-on practice in the console and a set of practice exams. The notes are strongest in the final weeks before the exam, when you need to consolidate rather than learn from scratch.

PDF. Each one opens in Google Drive for reading in the browser, or downloads directly so you can annotate it offline.
Please do. They were written to be passed around — share the link with anyone preparing for the same exams.
WCAG 2.2 and the POUR principles, semantic HTML, ARIA roles and live regions, keyboard navigation and focus management, colour contrast requirements, React Native accessibility props, and how to test with VoiceOver and TalkBack. It is code-first, so nearly every concept comes with the markup to implement it.
