The final exam begins exactly two weeks from today (April 27). Between now and then you need to complete all the Part 6 WebAssignments. These homework assignments count a total of 245 points. That's a significant portion of your homework grade for the semester.
Keep in mind that Part #6 is also heavily covered on the final exam. So if you neglect Part #6 you get whacked twice, once with regard to your homework average and again when you take the final exam.
We're nearing the finish line, and this is no time to slack off. A good understanding of Part #6 will be worth the effort.
