Jessica Wrbka

Cambridge Coordinator


Bachelor of Communications and Business management,
PostGrad Certificate in Education.

Teaching wasn't initially in Jessica’s life plan; she pursued a business degree before discovering her true passion. About four years ago, she embarked on her teaching journey in South Africa, instructing Accounting, Economics, and Business Studies in two different high schools.

During her teaching experience, she identified a shortage of Mathematics teachers, prompting her to pursue a certificate in FET mathematics. This decision not only allowed her to channel her love for mathematics positively but also opened doors to new opportunities, including the honour of teaching at Thames British School in Poland.

Jessica finds solace in books, thoroughly enjoying spending time with friends and family, and seeking new adventures, especially through travel to explore diverse cultures and traditions. Active in sports like netball and swimming, she embraces her South African and Portuguese heritage.

Her core belief regarding teaching is that it should revolve around teaching not just knowledge but wisdom. For her, teaching is about instilling confidence, accountability, and honesty in students. Through fostering positive relationships and demonstrating love, she aims to impart the wisdom that goes beyond subject content, emphasising the importance of being good individuals who act wholesomely and compassionately. The subject matter, she believes, is an additional benefit rather than the primary objective.
