What people say
This past year I have been preparing for the Proficiency exam with Sam. I just want to say that although I had to work very hard, it was completely worth it. He has very good teaching methods, focusing on everything you need for the exam, especially your weaknesses. Moreover, classes are very interesting, and an hour flies by very fast. I am very grateful that I had such a good teacher to prepare for this exam.
