Introduction

I recently passed the AWS Certified Solutions Architect - Associate exam. I'd like to share my thoughts on what I did to pass and some notes I kept along the way. Before beginning, it's worth considering what this exam is about.
AWS Certified Solutions Architect - Associate is intended for anyone with one or more years of hands-on experience designing available, cost-efficient, fault-tolerant, and scalable distributed systems on AWS.
The AWS Solutions Architect Associate exam is one of the most popular certification exams out right now for anyone trying to break into cloud engineering, architecting, or web solutions. It covers aspects such as technical deployments of AWS systems, AWS best practices, and other skills needed for competency and working within the Amazon AWS ecosystem.
This article gives you an overview which content and training material I used to prepare myself for the AWS SAA-C02 exam.

How did I prepare ?

I spend a considerable amount of time learning AWS before attempting to take the Certification Exam. It is important that you spend time with AWS for you to be good at it. The Resources I used while preparing I am linking them below one by one.

1) 📚 Courses I took: Initially, I enrolled in a course on Udemy called “Ultimate AWS Certified Solutions Architect Associate 2022” by Stephane Maarek which is a very good course and covers all the most important aspects of the AWS and its fundamentals so this is a very good start.

👉 More Information on the udemy course can be found here

2)🛠️ hands-on projects: Learning only theory won't help , you must work on some hands-on AWS projects. I would recommend you to practice some of the AWS projects from here or you can practice them from skills builder learning Center.

👉some of the projects I practiced are mentioned in my github repository.

3)📋 AWS Ramp-Up Guides: Your guides to learning the AWS Cloud.

AWS Ramp-Up Guides offer a variety of resources to help you build your skills and knowledge of the AWS Cloud. Each guide features carefully selected digital training, classroom courses, videos, whitepapers, certifications, and more. Explore the guides below by role, solution, or industry area.

4) 🤝 being part of a Study Groups: I also recommend you to be part of a study groups. it helps you stay focused, probably having study groups with people studying for the same exam is an added benefit.

Study Groups I was part of:

Cloud and DevOps Babies:

Cloud and DevOps Babies are a global group of babies with curious minds to learn/decode Cloud, DevOps and Microservices tech stacks.

👉 more details can be found here

Tech Study Slack: TechStudySlack is a Slack for people studying Tech

👉 more details can be found here

5)✍️ practice tests: Lastly I recommend all of you to pass these practice exams before attending the real exam. It provides simulated questions that are very similar to the actual exam.

One of the selling points of this practice exam is that each question contains detailed explanations that will help you gain a deeper understanding of AWS services. It not just explains what the correct answer is, but also explains why other answers are wrong. It is extremely helpful to make you recognize the difference between similar services.

6)📝 Notes: I outlined the resources I would use and a rough guideline of how I would approach studying. You should find something that works for you but have structure and commit to it.

Useful Study tips and tricks

As usual, more study tips and tricks to help you with the exam:

This exam is available through online proctoring so that you don’t have to travel to the nearby testing center to take this exam.
Additional handicap of 30 minutes for non-native English speakers is still available, so make sure that you have requested that.
Make sure you will use the flagging mechanism and reiterate the questions if you have time.
There is no penalty for guessing.
You can and should apply the same rules as in the other exams look here for more details regarding how to read a question and answers.
