Karolina taught a variety of products at our school, Business English, Professional English as well as preparation courses for Cambridge Exams, various conversation lessons and grammar specials. All her lessons were delivered with high quality, attention to detail, planned fulfilling the objectives and she always received top feedback both from the students and the team leaders. Furthermore, she led a number of seminars for other teachers and was solely in charge of corporate methodology, communication with corporate clients, regarding their curricuum, progress and various requests. Cooperation with Kaja was flawless. First and foremost I really appreciate her diligence and calm attitude even in the most stressful situatons. She is very attentive and has the student's best interests at heart..
