A fantastic self paced and flexible online learning platform
A fantastic and flexible online interior design course I am undertaking at The Interior Design Institute. The institute has created an online platform that is easy to navigate and communication is fantastic. The Modules I have completed so far have been full of relevant and invaluable information. I’ve learnt so much already. I love that the course is self paced so I can do this alongside my business and being a Mum, without the pressures of assignment deadlines. This is why I chose the IDI over the other courses out there and I am so glad that I did. Highly recommend.

Hi Sarwat,
We are so delighted to hear that you thoroughly enjoyed the course and found the learning experience to be fantastic! It's wonderful to know that the flexibility to learn at your own pace was incredibly convenient for you. Your high recommendation means a lot to us!
The course material has been brilliant, and my tutor is always there to help and has great advice.
I would give it 5 stars but I think a few more ‘included in the price’ tutorials would really help. Most of them are an additional cost. The facebook group that is run by the Institute is also really helpful and full of like-minded people.

Have started the course 5 months and really enjoy it as its very detailed and clear enough for someone completely new in that field.
The assignments can sometimes be a bit ambiguous to understand, however you get answers to your questions very quickly through your assigned tutor.
Would recommend it but discipline is definitely required as a self study tool.

We particularly love hearing that the flexibility allows you to balance your studies with your work schedule.

The course layout is exceptionally detailed and explains every concept clearly. I love the self-paced timeline, which allows me to study without pressure. My tutor, Laura, is incredibly helpful and responds quickly to any questions. A major benefit is that as soon as you submit a module, the next one is immediately unlocked so you can start reading and taking notes. Before starting, I knew nothing about floor plans, but the advanced module, along with the excellent video explanations, have been incredibly valuable. On top of that, the company has great communication and frrequently offers excellent promotional discounts on the course.
