Now that you are aware of the exam, here are some tips for completing your exam the first time.

Tip 1: Work with the Official Exam Guide Outline

The outline divides the exam into sections and organizes the skills required of a Professional Data Engineer.

Training is typically conducted in a ramp fashion, with fundamental concepts introduced initially and then more complicated and challenging concepts introduced later. The Exam Guide is not a study guide. As a result, it isn't organized for learning, importance, or procedure. It's laid down in the order that a group of experts thinks about the work.

The official videos do not cover concepts, but the Official Exam Guide lists all requirements. Make it the first step to getting familiar with the list to evaluate the status of your work while in your learning journey.

Tip 2: Take notes

We need to repeat the material to learn because neurons in our brains become linked together. The more abstract something is, the more essential it is to practice making those thoughts a reality. Going one more time through the entire video content is inefficient; therefore, I recommend writing your notes. By preparing your messages, you will attain much knowledge, so there will be less repetition.
Remember: practice makes it permanent.

I favor Diary for Confluence as it is the fastest way to create and maintain notes in confluence. Stay on top of your course and use confluence to manage your notes course logs.

Google recommends 3+ years of industry experience, including 1+ years designing and managing solutions using GCP to succeed with the certification. I am sure you can pass with a little less than that. Nevertheless, it is crucial to your success to have at least a few months of hands-on experience with Google Cloud technology.

Tip 4: Time Management and Planning

Create a timetable to anticipate and track your progress. The schedule should be based on the Official Study Guide from Tip 1, video content, and sample questions from a book or the

A quick tip: If you tend to procrastinate but are determined to complete the certification within one month, for example, just book and lock down the exam date by paying the 200 USD as early as possible. To make sure you can complete it on time, I propose you book the exam date one week ahead of your imaginary deadline. You could do it one month ahead if you want. You will be surprised that you will still manage to complete and pass the exam with the tight deadline you set for yourself.

Tip 5: Read the best practices on GCP

Use the GCP documentation to learn about best practices that are helpful for the test and your everyday work. The exam contains many questions about the type of service to use and how to set it properly. That is why the focus should be on all possible solutions and how they can be combined with other services, not just on Data Engineering.

Get familiar with the concepts of IAM and look for best practices of BigQuery, BigTable, etc. Here are some documentation pages you might find helpful. Of course, feel free to use other documentation as well:


All in all, you need to have solid Google Cloud knowledge to start with. If you are not familiar with the technology, the advised courses will not make sense to you. To get well prepared for the exam, I encourage you to complete the Official Data Engineer course videos and read about the best practices of GCP products, followed by the ML Crash Course provided by Google. You should be ready to pass the exam by combining your studies with your knowledge. Good luck!
