But don't despair!

Use the practice test as your guide as to what you should focus on
*Make sure to do the practice test!

Other pieces of advice:
-Obviously, review the lecture notes & this blog. But don't spend all your time reading!
-Try to do at least couple of the questions from each homework set without your notes, then check your answers. This will help you isolate your strengths and weaknesses.
-Check your old, completed homework assignments against the answer keys posted on Canvas. Make a note of answers that differ from yours especially if you don't understand why the answers differ. Make sure to ask about these questions during class, office hours, or the review session.
-Same goes for the quizzes we've taken since the last exam.
-Make a note of questions you don't understand from the practice test, and bring those questions to class, office hours, or the review session.
-Ask your peers for help. Form study groups. "Grade" each other's homework.
-Finally...

Don't panic



Friday 11/11:

I recommend that you start studying for Exam #2 now. 
In the course of your review... 
Please give some thought to what you'd like to review in our discussion on Wednesday, 11/16. Then, leave your suggestions in a comment below. 
Make sure to include your section time (9:30 or 11:30) in your comment.

I will update this post prior to our 11/16 discussion class.






Update 11/15 p.m.:

I haven't received any requests in the comments regarding what you'd like to cover tomorrow. Feel free to leave comments later tonight. In the absence of student feedback, we will cover:

-Questions about the practice exam
-Lingering questions about the homework
-Questions regarding the "identify the fallacy" examples Ami posted earlier this week
-A selection of questions from this 15 page set of practice questions I've created for you



In the absence of student feedback, I will focus mainly on generalizations, statistical syllogisms, polling, and causation.

I also want to review the answers to two questions from Quiz #5 that gave people trouble:



4. Most philosophers like cats. Liz and John are philosophers. Therefore, Liz and John probably like cats.

Name the argument structure: 
a) Generalization
b) Modus ponens
c) General causal claim
d) Bob
e) Statistical syllogism


6. Scientist testing new pain medication: "A dose of 50 mg causes the most pain relief and the fewest side effects. Below 50 mg, the rats still show signs of pain. Above 50 mg, the rats start getting sick." 

The above argument employs which of Mill's methods to reach its conclusion? 


a) Method of agreement
b) Joint Method of Agreement and Difference
c) Method of Concomitant Variation
d) Method of Difference
e) Method Man


Happy studying :)
