The students can be one person or a small group. The largest group I have is 5 people. One of my students is a medical doctor who wants to do a residency in the US and another wants to complete an MA in Public Administration at Harvard. These students have very high levels of skills, and I only have two small groups who are lower intermediate. I have approximately 10 different classes and people attend once or twice a week for one hour or one and a half hours.
Students are great and seem to enjoy their classes.
I have one group reading Snow Falling on Cedars in the Longman edition and we will watch the video together. It is the common greeting here. The school provides all text, tape and video materials and they are both American and British. At the present time American native speakers are requested more than British. All text materials are quite expensive.
