Comprehensive but NOT confusing!
After a warm welcome, I found it simple to navigate the website and student area. The modules are well laid out, thought through and include everything needed to guide and help you on your way to becoming a fully fledged interior designer!
You can do things at your own pace and there is no pressure of deadlines as such.
Your tutor is only a message away, should you need support, advice or to just check in.
All in all, I’d recommend this course.

It is not just general information on interior design.
My experience working with IDI has been very enjoyable and constructive. The same applies to the guidance I receive from my tutor, who monitors my progress in interior design. The guidance I receive is particularly important, always with kindness and useful advice, but also with a sense of personal contact.
The lessons have proven to be very practical, easy to understand, and rich in information about creativity in interior design!
In addition, the assignments are very useful and practical, as they help me apply the knowledge I acquire in practice and strengthen my desire to continue my studies.
I have attended other seminars and courses on interior design, but they have not managed to teach me what I have learned so far from IDI.

Great Course for Starting Interior Design!
Love the course thus far! The module PDFs are well detailed and thorough. Although I do wish, there are in depth videos of the modules to go along with the PDFs for visual learners who prefer that method of learning, I still appreciate how well thought out this course is in assisting me to start my journey as an interior designer. :)
