For a course entitled Scala 101, this course is pretty advanced, designed for those already familiar with enviroment, vocabulary and broad programing experience. I gave it a shot but I felt like it was a desastrous waist of my time. I strongly suggest you go back to scratching board and redesign it for people with no program experience, or do not classify it as "basic" or call it " 101". Those of us really interested in learn it would really appreciate that.
