Andreas thinks that the Study Centre is a form of one-to-one tuition. He is on Module 3 and needs to practice reading to pass the module.
At the Study Centre, he receives individual assistance. After each session, he brings home something new to read. It could be an article or a text from Wikipedia, for example. During the next session, he then discusses what he is read with his teacher. This strengthens his ability to understand what he reads.
Thanks to his efforts at the Study Centre, Andreas has improved his ability to read a text, understand it, and answer questions about the text. Therefore, he is much better prepared for his next test.
