• Woo hoo! Ive been
• studying for weeks already!

About the final

• 100 multiple choice questions, largely but not
  exclusively taken from 2nd semester.
• Only scientific, non-graphing calculators will be
  allowed.
• If you do not bring your own calculator, you will
  take the final without one! The test has been
  written so you should not need a calculator to
  solve the problems. NO sharing during the test,
  NO borrowing when someone else finishes!
• A periodic table will be provided for you.
