Are you thinking about pursuing a career as a Data Analyst or Data Scientist?

Do you ever think that your career could take a leap forward if you would have more knowledge and skills in the world of data?

Perhaps you are even feeling overwhelmed by the number of courses available or by the fact that your life is already too full to concentrate on one more course?


I am Nikolai Schuler, I am a data scientist and BI consultant, and I have been there too...

A few years ago I noticed that the world of data benefits from many new tools and technologies. However, I also realized that it is extremely difficult to get trained in the field: Practical courses with real quality content are rare and are often structured in such a way that they are incompatible with a working life full of other tasks and activities.

While going through hours of research and training, I came up with the idea of creating a course that would offer extremely valuable content but that would be at the same time easy to follow due to its structure.

My goal is to help as many people as possible to pursue their desired career in this new Digital Age by enabling them to upgrade their data analysis skills. I am proud to say that I am heading in the right direction as my courses have already found their audience in over 170 countries and received thousands of positive feedbacks.

The practice test offers excellent questions that thoroughly cover the subject matter and key topics for the AB-900 exam. What truly sets it apart is the detailed explanations provided with each question — they go beyond simple answers and dive deep into the concepts, making the test feel like a study guide in itself. The depth and clarity of these explanations make this resource incredibly valuable for exam preparation. I would highly recommend that the author consider creating a full study guide, as their ability to break down complex topics is outstanding.

Overall Great set of practice exams!!! The Practice mode is done amazingly here!! each answer is summarized and explained, even the incorrect answers explain why they are incorrect. Perfect for supplementing study! When you get an answer right, you can deepen your understanding, while getting an answer wrong means you will learn why it was wrong, and reduce the chances of getting a similar or related question incorrect. This method boasts a dynamic way to interact with content as you are no longer simply testing your knowledge, but simultaneously patching holes conventional studying tend to leave when applying theoretical knowledge. A few shortcomings.. Most of the questions are phrased more confusing than the actual exam, forcing you to read the questions multiple times focusing on keywords meant to "trick" you. The AB-900 exam questions are much simpler, some of them not even bothering to create an imaginary scenario, those questions are more like "You want to do X, what should you use?" Lastly, the exam contains GUI, and expects you to know how to navigate this. These dumps do cover settings, and configurations, but they are not accompanied by GUI, meaning in the exam even if you know an answer, you might not know where to locate it by interacting with the GUI, making you spend more time navigating the limited dummy GUI to try and find the setting you know should exist. Adding GUI elements on configuration questions would be a great quality of life update.

This training needs an update. The questions should be added. If you are preparing for the exam, these questions are not up to the mark. I had my exam yesterday, none of the question came from these 250 questions.
