The course was Great, Widhi is a true professional teacher. That mean, no chit chat, his instructions are precise, and even when he makes an mistake and immidiatly correct it, it seems as if he did it on purpose to humble show you what mistakes are common. He doesn't motivate you. Following this course is work. As someone with an adhd brain, that isn't easy. But hindsight its the best learning method I can imagine.
