Hi Atziri,
Thank you so much for your feedback—we really appreciate it 😊
We completely agree that having more video content alongside each module would be valuable, and it’s something we’re actively working on. We already offer a selection of videos, and we’re continuing to expand this library over time.
In the meantime, we also offer additional video-based learning through our MASTERSERIES with Darren Palmer, as well as regular live workshops covering a wide range of topics.
Thanks again for sharing your thoughts—it really helps guide what we improve next! If you need help, send us a message!

Diploma course review
I've really enjoyed the course so far. The modules are been relevant to what I expected I would need to have learnt, and have been really challenging! The additional support via online webinars and tutorials have been invaluable to the course so far.

It’s great that the modules are both relevant and challenging in the right way—that’s exactly what helps everything really click. We’re also really glad the webinars and tutorials have been supportive for you along the way.
Wishing you lots of continued progress and enjoyment as you move through the course!
Pleased & Impressed!
The learnings are immediately transferable and applicable in real life. There isn’t much fluff and this has been helpful to hone in and elaborate on some of my previous design knowledge. I wouldn’t say it’s as in depth as I had hoped, but for as much information as you do get from this short course, I’m impressed. My tutor is also very thorough and offers insight on every assignment. I love the application and how I can truly learn and do this course anywhere (even while traveling).

Thanks so much for your thoughtful review, Mari!
We’re really glad to hear you found the course practical and easy to apply in real life—that’s exactly what we aim for. It’s great that the focused, no-fluff approach helped you build on your existing design knowledge, even if you were hoping for a bit more depth overall.
We’re also so pleased to hear your tutor has been thorough and supportive—having detailed, personalized feedback can make a big difference. And being able to study from anywhere, even while traveling, is such a bonus 😊
Thanks again for sharing your experience—we truly appreciate it!

I have loved every bit of the assignments and studying! It has been brilliant for me to study at my own pace as I am still working full time as a teacher. The content is fabulous and the expectations are high, which is great.
If there were anything I’d like to see more of, it is maybe a register of people willing to teach or demonstrate Sketch Up and Layout in person in your local area, or even like a virtual meeting. As the only challenge I have found is trying to navigate learning these programs with written information - I think I would understand and learn more if I could see someone demonstrating and showing me.
Overall, I am so excited about this Diploma course and I am so pleased with the confidence it has given me.

Hi Nicole,
This was such a lovely read—thank you for sharing it! It’s great to hear how much you’ve been enjoying the assignments and that studying at your own pace has worked so well alongside full-time teaching. That’s no small feat, and it’s wonderful that the course is meeting you at that level.
We completely understand how challenging it can be to learn programs like SketchUp and Layout through written materials alone—it’s a very common experience, and many students feel the same way. At the moment, we don’t have a system in place to connect students with local tutors or live demonstrations, but we truly appreciate you sharing this idea. It’s helpful for us to hear where additional support could make a difference, and we’ll be sure to pass your feedback along to the team.
It’s so good to hear how much your confidence has grown—that’s exactly what we hope for. We’re really excited for you as you continue through the Diploma!
great experience !

That’s such a lovely reason to start learning interior design 😊 Creating a cozy home for yourself is honestly one of the best motivations, and it’s great that you’re also thinking ahead about possible extra income after the course. Wishing you so much enjoyment as you go through it and bring your ideas to life, Demi!
Incredible Course, Amplified Learning!!
What an incredible course offered by IDI. The course material is thorough, easily set out for clear understanding and so much interesting content. The additional masterclass videos which i paid for were so informative and added enormous context to assignments, making each one exciting to start and complete. The tutor support is awesome, only a mail away and feedback given is so insightful and genuine to help you grow your understanding and skill. I would recomend this course to anyone interested in starting out in the Interior design industry or just adding another skill to their toolbox.

We’re also glad the tutor support has been helpful along the way. Having that accessible, thoughtful feedback can make a big difference when you’re learning something new, so it’s wonderful to hear it’s supported your growth and confidence.
We really appreciate your recommendation and wish you all the best as you continue building your skills in interior design!
Great experience so far.
I’m currently about halfway through the IDI course, and so far I’m really enjoying it. The website is very organized, which makes studying much easier.
The PDFs in each module are quite long, but they really cover everything, so it makes sense why they’re structured that way. They also provide a lot of resources to help you in each module.
My tutor Meghan Yang has also been great, responsive, and very helpful throughout the process. Overall, it’s been a really good experience so far :).

It's a really good course
It's a really good course, concise and informative with fun assignments. The only draw back is accessibility to tutors, and I would prefer to fix errors in assignments before getting a pass to make sure I've done things correctly.

Thank you so much for your kind words—we’re really glad to hear you’re enjoying the course and finding the assignments engaging 😊
We completely understand your point about wanting to correct any mistakes before receiving a pass. Just to clarify, our course is designed so that assignments are treated similarly to exams, which means tutors aren’t able to provide feedback prior to submission. That said, if your tutor feels an assignment hasn’t been completed to your full potential, they can reset it and give you the opportunity to review and improve your work.
We really appreciate you sharing this feedback—it helps us understand what matters most to our students 💛

I couldn’t be happier with my decision to study Interior Design! I’m honestly so excited and completely over the moon about this journey ahead of me. From the moment I started, I felt inspired and motivated to explore my creativity in a whole new way.
Interior Design has already opened my eyes to how spaces can truly impact how people feel and live, and I love learning how to bring beauty and functionality together. Every step feels like I’m getting closer to something I’m really passionate about.
