From my experience with the first iteration of this course and with the problems experienced by people on the course forum ... 99.99% of problems came from NOT reading the assignment.
I went through all the homework and passed the course with the maximum grade. Except for the last homework where I too was guilty of the above, all submissions took the maximum grade from the first try. I don't remember encountering any confusing problem definition and even if a problem is confusing to you, there were plenty of people available on the forum and all you had to do was to ask for clarifications.
Also, in regards to solutions, there were really helpful advices in the assignments' source-code. Sometimes all you had to do was to translate English to Scala.
