Hello everyone, I hope you’re doing well. I wanted to share my experience with preparing for the PL-300 exam, which I took and passed recently. In order to improve my knowledge in these areas, I went through all the Microsoft Learn modules that were created to prepare people for the PL-300 exam. This helped me cover all of the topics in Power BI exam.

To really solidify my knowledge in the subject areas, I made sure to go through all the Microsoft Learn modules that were specifically created to prepare individuals for the PL-300 exam. Trust me, it was well worth the effort! These modules covered all the important topics related to Power BI, leaving no gaps in my understanding.

But I didn’t stop there! I wanted to ensure I was fully equipped and ready for the exam, so I took advantage of the practice exams provided by Microsoft. In addition, I decided to complement my preparation by enrolling in a comprehensive Udemy course. Through Udemy, I completed four practice exams (each taken twice) and even engaged in a practical case study. Let me tell you, the Udemy course was a game-changer for me. The practice exams there closely resembled the actual exam questions, providing me with valuable practice and boosting my confidence.

For those of you who are currently on the PL-300 exam journey, I’d love to share some of my thoughts on how to prepare effectively and highlight specific topics that deserve your attention. When it comes to practice exams, I found that the ones provided in the Udemy course were particularly valuable. They accurately reflected the types of questions I encountered in the actual exam. As for the visualization questions, they were relatively straightforward as long as you have a good understanding of basic best practices for selecting appropriate visuals.

Now, let’s talk about the DAX-related questions. These constituted a significant portion (about 40%) of the exam in terms of scoring, if not more. To excel in this area, make sure you have a strong grasp of the following:

  • Understanding filter context and the functions that can override it.
  • Familiarizing yourself with time-series functions.
  • While there were only a few questions, it’s worth brushing up on the advanced forecasting, AI, and ML features.

Approximately 40% of the exam focused on optimization, whether at the query or report level. Here are the key aspects you should pay attention to:

  • Mastering the use of Power Query Editor, whether it’s working with M-code or utilizing the user-friendly interface to combine tables, control refresh operations, and more.
  • Exploring the powerful features in Power Query that can help you set primary keys (PKs) and enhance your data model.
  • Taking advantage of the built-in optimization analysis features.

Lastly, it’s worth noting that at least 20% of the exam is focused on Microsoft-specific products. Here’s what you should focus on:

  • Understanding how Azure seamlessly integrates with Power BI Premium (the cloud service), including its data storage and security features.
  • Familiarizing yourself with organizational-level security and the features covered under Microsoft 365.

I genuinely hope you find my insights helpful and that they contribute to your success in the PL-300 exam. If you have any other tips or questions, please don’t hesitate to share them with me.
