text: 15 people directly from the Summer School 2 and 15 people from the Test 4 will join the Winter School 2, which is held at the same place with Winter School 2. In the school, students stay only a week; studying theories in the morning and learning experiments in afternoon. Almost all of the theories are related to Organic Chemistry.
