the first 2 classes are too slow and the 3 too fast. It is a good first approach to the course if you don't know anything about it but in my case the new subjects came to me all the last day when there was no more classes left ahead (all the most complex subjects where very superficial). We never reviewed the homework and the teacher didn't encourage to share people's experiences with the others, questions, achievements where all private. I think it is really necessary to open a second level class to make it worth it to people with a bit more knowledge in the subject and for continuity.
