Kathrin Aitken Bahasa Indonesia student

I started with the Beginner 2 program. Before that I used an app to learn Indonesian but the courses of SIB school helped me a lot more to improve my bahasa skills. The weekly sessions with my teacher are very insightful and I am gaining knowledge from a native speaker. Now I can have short conversations with taxi drivers for example.

Silvia Colabruni IELTS Student

I needed a high IELTS band to work in Italy. SIB School gave me confidence, structure, strong conversation and listening skills, and stronger grammar. My final IELTS band was amazing and I landed a great job in Italy because of my English. I definitely recommend SIB School for English learning.
