Over five years ago, I took my first steps into Google Sheets and Apps Script through Ben’s courses, and that really marked a turning point in my professional journey. What started as simple curiosity ended up becoming a core part of my work. Today, these technologies underpin the systems I build for my CommunitySensor methodology, supporting data-driven mapping and sensemaking of collaboration ecosystems. While I’ve continued learning from many sources over the years, Ben’s courses were the ones that gave me the initial confidence to start building my own automation tools. I’m currently deepening my skills further with his Modern Google Sheets and 28 Days to Gemini Mastery courses, and I still recognize the same qualities that made his earlier courses so valuable: his gentle, encouraging way of guiding you through the material, his professionalism, and his well-timed sense of humor. He doesn’t just explain things, he helps you grow into them, giving you the confidence to explore, experiment, and build your own solutions.

I’m currently completing the '28 Days to Gemini Mastery' course, and it has been incredibly insightful. The content is a perfect blend of refreshing my existing knowledge, giving me the confidence I lacked, and introducing me to powerful tools I didn’t even know existed. Applying these new skills is already helping me streamline the 'boring' admin tasks in my role. Ben is a fantastic instructor; he moves at a perfect pace and explains complex points with great clarity and understanding.

Ben Collins' 28 Days to Gemini Mastery course is a must for anyone who wants to get up to speed quickly on using Gemini. I am a little over half way through the course and have upped my skills significantly. In particular, I want to point out The Day 8: Advanced Prompting course. Ben's recommendation to structure your prompt using his Role, Goal, Context, Constraints, Output (RGCCO) method provides noticeably output from your chat with Gemini. I am looking forward to completing the course and will add to my review at that time.

I rely on Ben Collin's courses to keep up with all of Google's empowering new tools. 28 Days to Gemini Mastery is fun, easy to follow, and instantly upgrades my habits. I chose this course primarily to build agents, and everything along the way has been full of sparkly nerd gold bling.

As usual with Ben Collins, this is a brilliant course. He always manages to keep the lessons short but comprehensive. No fluff! I feel that the technical level is perfect too. Thoroughly enjoyable and the scariness of our new AI world has been moderated greatly. Thanks Ben!

This course was outstanding! It offered just-in-time learning that perfectly fit my schedule. The content was engaging and effectively demonstrated how Gemini integrates into the Google Workspace ecosystem. I appreciated the excellent examples that highlighted the differences between Gemini for education and its consumer version. I highly recommend this course and all the offerings from Ben Collins!

The named functions portion is gold. I've already created a couple that I use frequently. Lots of great info!

I'm halfway through the 28 Days to Gemini Mastery, and I'm absolutely loving it! Content is practical and very well explained with practical examples and use cases that can easily be translated to different contexts. I can immediately see how to apply most of this in the work I'm doing. For me, the best part is seeing how the different tools can be used together to build AI-supported systems for knowledge management and knowledge sharing. Highly recommended course! (And in case it's not clear, this is a fully human-generated review ;-) )

5/5 Stars – Another Masterclass by Ben! Highly Recommended! This is the fifth course I have taken with Ben, and once again, he has delivered exceptional value. If you want to truly master Gemini and integrate it into your workflow, look no further. The structure of this course is fantastic. It is meticulously organized, taking you seamlessly from the most basic operations to highly complex, advanced techniques. What I appreciate the most are the examples—they are incredibly interesting, practical, and perfectly focused on real-world scenarios. As always, Ben is a phenomenal instructor. His teaching style is incredibly clear, which is a huge plus for non-native English speakers like myself. He explains complex AI concepts in a way that is easy to digest and immediately applicable. Thanks to Ben’s courses, I have gained a massive competitive advantage over my colleagues, especially when it comes to leveraging Gemini within Google Sheets. His insights have genuinely transformed the way I work and boosted my productivity. If you want to stay ahead of the curve, do yourself a favor and enroll. Thank you, Ben, for another amazing course!

28 Days to Gemini Mastery The rapid advancement of AI has brought a significant increase in workplace expectations, I feel I’m required to do double the output in half the time - without sufficient training. Ben's course has been invaluable by cutting through the hype and providing the essential principles I needed for a strong foundation. Currently at the midway point, I am already experiencing the practical advantages of his guidance, particularly in how I structure Gemini prompts and utilise Notebook LM to produce superior results and spark new ideas. I am eager to complete the remaining lessons and explore future courses. Many thanks Ben! Chris

I am really enjoying the course. In particular the use of tables is something I had not considered before, I can now see that there is much more to them and I can already see practical applications in my work that will make the work quicker and easier. The same applies to several of the formulas Ben has covered. Subjects and concepts that initially seem daunting become much more straightforward thanks to Ben's engaging and accessible presentation style. The short lesson format combined with the downloadable templates is also very helpful. Thanks Ben!

This course is highly beneficial as it teaches you how to effectively utilize Gemini across the Web, Google, and the Gemini environment. The best aspects of the course include its practical examples and the convenient accessibility of resources. Slides, instructions, and prompts can all be easily downloaded or copied from the course website. Furthermore, you have the flexibility to revisit any of the previous lessons whenever needed.

28 days to Gemini Mastery - very practical and informative, I'm learning a lot which will help me and, by extension, our small team, get the most out of our Google subscription. The Canvas feature in Google Sheets blew my mind :)

5-Stars. These Gemini tutorials are helping me realize my dreams by demonstrating robust new ways to go from concept to reality. This series is so much more than just prompt engineering - and it even improves your approach to those!

Really good course, they're short and sweet without the fluff. I feel more empowered to do more automated things as a product owner and not use spreadsheets as if it was 2010 all over again.

I signed up for "Beginner Apps Script" right after completing Ben's "Introduction to Google Apps Script" course. If you're thinking about signing up for this course and you've completed the "Intro" course: do it. While Ben does review topics from the Intro course, he goes into much deeper information on those topics (so if there was a moment you went 'Huh?', it makes so much more sense here!). Further, this course. has really opened up a passion -- that I didn't know was there! -- into programming, and I've begun to learn Python! It's kinda cool learning a new language and seeing how the ideas Ben taught here connect! Thanks again, Ben!!

I teach coding to middle school students, this year focusing on using Google Sheets to create Relational Databases. I also use Google Sheets for many tasks in the Admissions, Development and Business office of our school. Ben's enthusiasm for the various topics in this course is FABULOUS, and I can regularly be heard yelling "that's awesome!" while watching the videos (much to my officemates' amusement). I've shared some of what I've learned in this class not only with my students, but with colleagues and other spreadsheet-geek friends. Having the sample sheets for each topic has also helped me go back and really use a function in my own work.

As always, Ben has developed and delivered a high-quality and content-rich accessible course to enhance the users knowledge of Google Sheets. This practical set of lessons and examples are easy to follow, yet complex enough to know you are really learning how to best leverage sheets for a variety of purposes. I really appreciated the attention in leveraging generative AI in conjuction with Sheets. I consistently recommend his courses to colleagues looking to further their understanding and use of Sheets, Apps Script and more! Great job once again, Ben!

We transitioned from a Microsoft Office to Google Workspace a few years ago. I had the Excel skills, but I wanted to become more productive in Google Sheets. Ben Collins has the best courses!!! I get all my Google certifications through his program. I'm currently earning my certification is his newest class called Modern Google Sheets. I'm so impressed with the results so far that I have already put them into practice at work (literally right now), and I can't wait to share them with my team.
