 So, if I can have your attention, let's go over a few announcements here. And these are the announcements for Friday, April 17th. Most of these announcements should just be reminders, and I'll leave this list up as we're going over them so you can take note of anything. On Blackboard, you had a pre-lecture quiz for today. In addition to the one for today, make sure you're checking online this evening and over this weekend. We'll give some ones up for next week, so make sure that you've prepared and done the one for Monday. Also, you'll look for your online resources, and that'll be where we put some of the keys and practice problems that we've had for some of these previous lectures. For today, we'll also put the recordings of these lectures in there, too. On WebAssign, you've got homework number 12 due tonight. You should have been working on this over the last week and a half. If you do run into any questions at this point, you can send those as ask your teacher request. I will be on checking tonight and tomorrow, so I'll still have a chance to answer those questions. Also remember that both your extra credit homework and homework number 13 are available on WebAssign. So as soon as you finish up homework number 12, get started on those other ones right away. I gave out in class last time the instructions for WAC number four and the optional WAC. Again, if you have questions on those, send those to me via email or ask me on Monday. They're not in due until the last week of class. I'll also have more information for you on the final exam in class next week. I'll leave these up here for just a minute so that you have a chance to take note of all these things.
