On the topic of what material will be included in the final: Given the cumulative nature of what we’ve been doing, there is a sense in which the material will cover the whole semester, although for the most part it will be more focused on things like what we’ve been doing in the later part of the course.
When you are looking at the practice finals, it is probably worth keeping in mind that the previous years got a little bit further. In particular, they had seen the wh-movement and islands stuff about a week earlier in the semester, rather than right at the end. So, there are a number of questions on these practice finals about identifying islands or doing wh-movement. These won’t be featured as prominently on this year’s final, though I still might have a question or two. So, don’t panic if you feel like there’s a lot of stuff in the practice finals based on the material in the very last lecture of the semester.
In general, I consider anything we covered in class or was part of a homework assignment to be “fair game” for the final, and the practice finals should give you a pretty good idea of the sort of thing I’ll be asking about.
