Student Reviews
What Our Students Says
The class was very educative and insightful. I learned a lot within the 3weeks of the virtual class. Before now I did not know how to use Excel worksheets, for example: data cleaning, creating pivot tables and charts, and lots more. After this intensive, interactive, and intellectual virtual Excel class. I have the confidence to handle any work in Excel.

The Excel Class was well-organized, and the pace of the sessions was just right. The instructor was approachable and created a supportive atmosphere that encouraged active participation, was responsive to queries raised during the class, and she also encouraged participants to reach out for clarification outside of class hours. The course content covered a comprehensive range of Excel topics, starting from the fundamentals and progressing to more advanced features. Overall, the Class was a worthwhile investment of time and money.

At the end of last year, I was very intentional about signing up for an advanced Excel class, to improve my Data Analytics skills. Thanks, to Trevotech Academy for bringing my dreams into reality. I enjoyed the online class because I had a tutor whose class was well-planned, and easy for me to follow. The assignments and project, were my best experience, as it was very beneficial to my learning process. Now I can confidently use the power query, and pivot table analyzer for analysis – Also, understand the purposes and steps for data cleaning. Thanks
Adara Ruth Oluwafunmilayo
I had no basic background or prior knowledge in tech and by diving into Data Analytics, Trevotech made learning easy. Our tutor was very great and she ensured all members of the class understood what was being taught before moving to the next topic no matter how long it took or how many times a particular question was being asked, she was really patient with everyone. She also gave relatable and live examples that made us understand better and she made sure she carried everyone along. I am glad I was able to participate in the class. It’s been a wonderful experience.

I was one person that was scared to start the class, because I wasn’t a computer guru, plus, had no knowledge whatsoever of data analytics. But I thank God for giving me courage and always assuring me that I can do it. Our Excel instructor was so patient ooo … geez she’s patient and friendly, I wasn’t much of a talker or question asker in class, was more of a silent follower. Also grateful for the class recording which allows me to go back and play it whenever I’m lost. Geez 💃💃💃 I did it. All Glory to God.

The Analytics class was beyond my expectations and very insightful. I gained alot in using excel for data cleaning and transformation using excel analytical functions and creating a report from the cleaned dataset. The tutor is very calm, experienced, and professional. She takes her time to explain each and every concept well so that every student will understand. This training has steered my data analytics career path with a strong foundation and also made the career path a promising one. Thank you Trevotech.
