Classroom Etiquette
You may observe behavior in U.S. classrooms that would be considered inappropriate in your country. Many students sit in class with their feet on the chair or desk in front of them. Some may have laptop computers in class. These behaviors are completely normal and acceptable. Students may also interrupt lectures to ask questions or to disagree with what the professor is saying. American professors are usually pleased when a student has a question or comment.

Open Door Policy
Professors who teach at U.S. universities have an open door policy when it comes to providing students with extra help. If you have a question about an assignment, you can set up a time to meet with your course instructor during his or her office hours. A teacher's office hours are generally listed on the course syllabus you receive on the first day of class.

Attendance
You should always be present on the first day of class, as this is generally when the professor distributes a course outline. Many faculty members are strict about attendance, and in some cases, students can be dropped from the class for excessive absences. Missing class means that you miss out on the notes for that day, and in some cases, surprise quizzes or tests.

Holidays and Breaks
You'll find that most of your fellow students will leave campus during the various breaks in the school year and during the summer. In fact, your residence hall may actually close down during these times. At these times, you may want to rent a car and see some of the country or travel to a friend's hometown.
