No, 5500 is a bit worthless and a bit deceptive. The lecturers are all 1 year or even less than one year of 3d software training. They have no experience in exhibition design. They talk about little knowledge every day for a long time and have no handouts. I really want to learn design well. Personally, I suggest learning from the design of exhibition companies. Now many exhibition companies also train design, and the tuition is cheap.
