very interesting course; the subject treated here seems to have wide applications in geometry and number theory; the weekly assignments were challenging at times but very thought provoking and I very much enjoyed myself during the course despite some minor flaws

Very good course. I have really learned a lot from this course. The excercises are carefully selected.

After having had a long lasting personal interest in modular forms, the miracle happened: this MOOC was offered. A huge thanks to Pr.Gritsenko for providing such high quality content and exercises, which go way beyond the classical theory. This is a very challenging and stimulating course which opens into current research areas. Again, a very big thank you to the organisers, if you are interested in the topic and are not working in academia, this is an absolutely unique opportunity !
