Class Discussion due 20120422
What!?! Spring Fair is this weekend. As such, I'll consider reserving a room and leaving a pile of tests on a table for those who want to come in and sit to take the test. The goal is to let you guys come in freely on Friday 3-7 PM. (4/20/2012). Though I recommend when you come, you commit to staying for an hour block. Perhaps I will come in and out to check. But I hope everybody enjoys Spring Fair, minus the one hour they come.
Then Friday 3-7 PM, we will do it again (4/27/2012). I will make the exam available online for those who can't make it.
In addition, I will make a test that you can work on before each Friday. That's 4 practice tests!
Hint 1: It will be based on your homework. Why? 1) That's most likely how Dr. Brown will write his test. 2) If you get a problem wrong, or don't know how to do a problem, then you'll know which problems you'll need to do more of. 3) In order to write more, I have to somehow make it easy to write.
Hint 2 (for first two practice tests): There will be 8 problems. One of the problems will try to ask something from the first half of the course (in minor preparation for the final). One of the problems will involve polar coordinates (Section 10.4). One of the problems will be an improper integral. The remaining five problems will come from Section 11.1 to 11.7.
Advice: Do all the problems from Section 11.7.

Class Discussion due 20120410
Check your email regarding the Practice Test Session.
For the Homework Buddy system, you're suppose to put A2D (agree to disagree) in the situation where you've discussed the discrepancy and somehow feel your answer is right and the other person won't listen to you. Otherwise, you should typically convince the other person why your answer is right and get them to change it. Future checks of the use of A2D will be more strict. And in general, listing another person as your Homework Buddy should mean ALL your answers match up. Perhaps not the work, but at least the answers. For now, I will also reduce the Homework Buddy bonus from 5 to 4. Until better use of the system occurs
