Such things as having someone else complete an assignment for you, copying someone else's work and submitting it as your own, or looking at another student's work during a test to get an answer are all considered cheating in the United States. Most teachers prefer or require you to type papers or reports in a specific manner. If you do not know how to use the word processor, the school will provide instruction for you. If you can't type or don't have a typewriter or computer available to you, you may want to consider paying someone to type your papers. Talk with other international students regarding their habits.
Many schools offer courses on how to study, which can be very helpful to new students.
A common rule to follow is to spend 2.5 to 3 hours in preparation for every hour of class time. However, be sensible. If you study all night for a test, your mind won't function well during class. And if you leave no time for social life and relaxation, you will become frustrated and lonely. Each college operates differently.
