Lot's of errors in the course. Wrong files. DAX part is very poorly explained. No exercises using DB connections, only excel. In real life most developers work with DBs.

Too many topics into one module and all important topics which need to be done properly are put together in one course making it look stupid

This is all a mess, it is just a guy reading the lectures, some of the exercises had mistakes and inconsistencies and borring.

The Exercise and File Provided for the Exercise are completely different and I can't even do single exercise in the Course

poor quality of exercises, advertisement-based content, can besqueezed in 60 minutes without any content loss

cant do tests

pure garbage

So, I just survived the “Optimize your model for performance in Power BI” bootcamp. My brain is still doing cross-filter directions in its sleep. Here’s my takeaway: Why optimize a data model? Because apparently, Power BI doesn’t appreciate when you dump a gazillion rows on it and expect it to run smooth like Netflix on WiFi. You want speed, less lag, and no frozen dashboards that make your boss stare at you like “seriously?” DirectQuery vs Standard models: Think of it like ordering pizza. With Standard (Import), you bring the pizza home, slice it, and it’s always there when you need it. With DirectQuery, you’re calling Domino’s every time you want a bite—faster in some ways, but if the network’s down, you’re eating sadness. Aggregations: AKA Power BI’s cheat code. Instead of dragging all the messy data into a report, you give it a neat little summary and say “Here, just work with this.” It’s like sending the CliffsNotes instead of the entire novel. Honestly, I learned that optimization is basically just adulting for data models: keeping things clean, efficient, and ready to impress without crashing under pressure. Now, my question to you all: If Power BI were a superhero, would it be Flash (speed) or Hulk (power)? Or maybe just Batman with too many gadgets (features)?

I found the Power BI course to be extremely valuable in expanding my skills and knowledge in data modelling, DAX, and optimization techniques. The materials provided were clear, well-structured, and hands-on, making complex topics like creating different data schemas and optimizing DirectQuery models more accessible. The DAX lessons were particularly helpful, and I appreciated the emphasis on performance optimization. Overall, the certification and resources offered were top-notch and have significantly enhanced my ability to use Power BI effectively for business decision-making. I would highly recommend this course to others.

It was a good course worth your time unlike the previous two of them(they were too long) but be aware most of the exercise files are different than they mention, i don't understand why don't they fix it although a lot of people reports the issues, anyway the explanations (readings and videos) are fine.

Really good content. Appropriate level of abstraction as well as good run through of practical application in the Microsoft Power BI environment. Plenty of data modeling tools and concepts covered and a good foundation for further investigation into DAX, PowerQuery and other features.

I enjoyed every single valuable seciton of this course. I would hightly recommend every person who has an analytic role in an organization to take this course.

The course was quite challenging and quite a detailed with regards to the core functionality of Power BI.

Upon completion, you will gain the skills to create and manage data models in Power BI. Great course!

This course was full of valuable and great information in terms of definition of power bi performance

The course provide very clear explanation of key concepts in a very succinct fashion.

very informative and useful details explained very smoothly and easy way

It is the best place to get ready yourself for future journey

This course is one of the best courses I have enrolled in.

Best Hands on explanation on Power BI Data Modelling

fully satisfied with the process of learning.

A very thoughtful and well structured course

Very good structured and easy to follow.

Some modules are so long, but is ok!!!

Very clear and in detail explanations
