Most short-term study abroad programs take time out of your vacation or personal schedule, so it is important to make sure the program offers enough classes during that time.
To make the most of your short stay, focus on one-on-one classes instead of group classes, which may require schedule changes. If possible, try to take six or seven one-on-one classes each day.
Do not try to learn everything in a short period. Focus on speaking and expressing yourself. You can ask your counselor for advice during your admission consultation.
