Generally speaking I think the course content is good, but I rated this course average because of three main reasons.
1). I think a little more effort to organize the material would go a long way. For example, the grammar presentations refer to new vocabulary words that were not introduced in the vocabulary list, and the vocabulary exams refer to content in the grammar section. It would be nice if the curriculum were designed so that you could study the vocabulary, take the vocabulary exam, then review the grammar and leverage what you learned in the vocabulary section to re-enforce your learning.
2). I also think that some of the topics deserve additional clarifications, and the presentations themselves are very short. I appreciate the length of the presentations when reviewing the presentations to refresh my memory, but difficult concepts sometimes require more attention than they are given. In some cases, it seems as though an elegant choice of words to describe a difficult concept is more important than taking the time to deconstruct that concept into simple phrases.
3). Lastly, there are errors in the presentations and exams, and little to no involvement from the professor to clarify points and/or correct those issues. I have noticed comments from students who have reported the same issues for the past two years, and those issues are still not corrected. I used to comment on the message boards for clarifications and to report errors, but after getting zero responses from the professor I stopped participating.
Conclusion:
Overall, I think it's a good course - it provides a good structure for learning the Spanish language despite the above shortcomings. Although they appear very simple to address, I see the same shortcomings exhibited by every course in the series.
