## GETTING HELP

Help with mathematical problems:
• Section:  Ask questions in section --- this is one of the main reasons why sections exist.
• Office Hours:  You are strongly advised to take full advantage of your professor's and ta's office hours.
• Classmates:  Sometimes a classmate can help. Sometimes you can learn by working out problems together with your classmates.
Help with personal problems which affect your class work:
• Talk to the professor or, if appropriate, your college provost.
