My Experience Taking the MS-900 Course Taking the MS-900 Microsoft 365 Certified: Fundamentals course was a valuable and rewarding experience. The course provided a solid foundation in understanding Microsoft 365 services, cloud concepts, security, compliance, and pricing models. It was particularly helpful in connecting technical concepts with real-world business scenarios. I found the course to be a good match for me because it balanced both technical and business perspectives. As someone interested in IT systems and cloud technologies, I appreciated how it introduced the core features of Microsoft 365—such as Teams, Exchange, and SharePoint—without requiring deep technical expertise. The structure of the course made it easy to follow, and the practical examples helped me understand how Microsoft 365 solutions can improve productivity and collaboration within an organization. Preparing for the certification exam also strengthened my confidence in discussing cloud concepts and Microsoft services professionally. Overall, this course gave me a strong foundation to pursue more advanced Microsoft certifications and helped me understand how cloud-based tools can support digital transformation in modern workplaces.

Good course to start with. I recommend you also visit the Microsoft Learn site. If you want to pass the official exam beware that the questions are very in depth. The questions in this course and the practice exams on the Microsoft Learn site are easy. Real exam questions are more difficult. You really need to know the details! I also got some questions about Copilot.

By Hector Robles on 9/9/2025

Very good supplemental information that other courses did not provide. May want to include some information on the support levels for different account types. I have gotten some questions on practice tests related to support and response times 24/7, 4-hour, 1 hour, concierge...

"Helpful update and easy to follow" The updated version of the course is much better. The instructor is clear, and the content is now more detailed with demos and improved lectures. It’s beginner-friendly and helped simplify a lot of confusing topics. With some added practice tests, it could be perfect.

By Charles Antwi Takyi on 6/5/2023

Excellent class, I am so appreciative and have a ton of notes. I will add the sources to my notes and practice what i have learned to enhance my skills and abilities towards work.

By Montserrat Frias carazo on 7/1/2022

Speech speed is a bit slow so I would recommend to play the video on 1.5 speed. The content on the is good but very superficial. You'll definitely need more than just this videos to pass a certification Hel yourself by reading the study guides included on the first modules. Added to the Microsoft 365 Fundamentals: MS-900 +Practice Questions course here on udemy and the practice questions included on the microsoft certifications website, you have a higher chance to understand everything related to MS900 and get the necessary score to pass the certification exam

By Anonymized User on 12/22/2020

This course is outdated at this point - 12/2020. There were a variety of updates in July 2020 for the exam but they are not reflected here. Additionally, most of the material is glossed over in the lectures or gone through rather quickly. If you are brand new to MSFT cloud, this would make it difficult to follow and retain. The study material helps fill in gaps, but it's not called out within the lessons which is a miss. At this point, I will definitely be looking at other options to round out the training so I can ensure passing my exam.

By Anonymized User on 10/1/2020

Very useful and easy to follow/understand. Some concepts are more of a review, but others are new to me and it was great to get acquainted to them.

By Anonymized User on 5/26/2020

The Course was really good and i hope it will help me to complete the MS 900 Certification exam which i am planning to give tomorrow. Demo videos are also nice , practical scenarios we are able to understand from them. Last but not the least i would like to add one point , can it be possible that you can arrange some practice test for us after completing the course. It will like a Mock exam for us before giving the MS 900 Certification. Thanks for the MS 900 Certification Course.

By Lisa Burnett-Waller on 5/6/2020

I was very impressed with the information presented in this course for the price. Thank you so much Skyline; I'm looking forward to taking the MS100 & MS101 next step courses outlined in your closing lecture.
