If no one has time for the entire practice exam, maybe someone could check the first 8 multiple choice conceptual questions? That would help a lot.

I, along with many other homework helpers, am not going to open a .doc file from a university website. Repeat those questions for which you are unsure of your answers.

In general, you are much more likely to get help from people at this site if you
  • Make it easy on us. Put the question in the post. Expecting us to open some potentially virus-infected .doc file just to see the question is not making things easy on us.
  • Show some work.
  • Keep the post limited in scope. Which problems are you specifically having problems solving?
