Thank you for your fantastic feedback Jaylynne! It's wonderful that our tutors' feedback is helping you improve and build your portfolio.
I just finished module 10 today. I am finding components of the course, enjoyable such as learning how to make mood boards.
It would be great if the course could be delivered in a way that is more inclusive to different types of learners. I’m definitely a visual hands on learner and it would’ve been incredible if there were videos as well as reading at the start of each module to learn the new content. I also find some of the programs like floor planner, a little bit clunky to use.
