"I am really impressed with their professionalism"

“I am really happy so far with my experience with QC Design School. This is my first time doing an online course and I am really impressed with their professionalism. From my first inquiry, they replied back quickly and were very helpful in answering my countless questions. As well, I was expecting to have to wait a week or more to receive my package and instead, it arrived two days after I signed up! I enrolled on Monday, Feb. 6 and my books and art kit arrived on Feb. 9th. WOW. After reviewing everything in my course (outlines, books, assignments, etc.) I cannot wait to get started! I look forward to all that awaits me on this new path of becoming an Interior Designer, Home Stager & Organizer.”

Michelle Joyce

“I liked how you could work at your own pace. It has given me a solid foundation to build my organizing business. I am looking forward to completing the Feng Shui course, and then more. I am so glad that QC offers courses in all the different design areas. It is hard to find that outside of a traditional 4-year degree. Thank you!”
