“EXCELLENT COURSE
Jellyman is an excellent teacher! His content is interesting, applicable and well-explained.
He has clearly thought about the way people absorb information and doesn't gloss over any assumed knowledge like many other courses do. He has taken the time to go through methods & concepts step by step so it's almost impossible not to learn!

“JOINS WERE HOLDING ME BACK
Great – this was holding me back but not any more

“STILL LEARNING THINGS
I was wondering why we were just now covering joins when it's something I felt essential enough to be a beginner subject. Then you delved into joins versus relationships versus blends and it became much clearer – this was more complex than an entry level subject.
Great explanations all around and I have a better understanding of when to use which tool.
Update: Just finished LODs. Mind continues to be blown! Can't recommend this course enough.
