• When you first arrive in class:
– If you have any questions about the homework
please put the question #’s on the board
• If someone has already put your question # up, and
you’d like to see an explanation, please put a check
mark next to the problem
• The idea being that problems that lots of people are
finding difficult will be clearly marked
• We’ll start with ≤ 10 minutes of Q+A

Exam #1: Grading
• Grading will be more detail-oriented than on the
homeworks
• Probably about 10 questions, ~10 points/question
– For all questions, ONE POINT for the correct answer
– Remainder for SHOWING YOUR WORK and for
CHECKING YOUR WORK
• Checking (where possible) will be required, and worth points
• I’ll try to make it clear on the exam which questions you
HAVE to check your work on
– You will need to write out any formulas, before you use
them.
