Beginning Java Track

I just finished the Java Lists and Java Interfaces as part of the Beginning Java Track and I have a few comments. First, these are incredibly misplaced. Lists is understandable where it is placed, but it explicitly says that it should come after Interfaces. I found that confusing at first, thinking there was something I should know. Second, Interfaces does Not belong there. It was almost impossible to follow as the instructor expected we had mastered concepts I have never even heard. It was terrible and I only sort of understood any of it. Third, and no offense to the instructor, the quizes for those were the Only times I have Ever had to give up on a question because I had No Idea what the answer might be. They are not as intuitive as you apparently think. (Think, fill-in-the-blanks.) I also found the switch to IntuitJ jarring and confusing. I have, apparently, not been on the right Track to have learned what that is or why I might care. And, since I do not have any idea why I would choose to use that, the short cuts that might otherwise not be there did not do me Any good. Please, Please update this track to make it make more sense. Right now, I feel frustrated and that is not conducive to wanting to continue.
