I studied French last summer at the Institut Monte Rosa school and can share my impressions.
The school is very beautiful! Stunning territory, very well-groomed, lots of greenery, beautiful buildings, near the lake, where you can swim and go boating. As for living conditions, it's also impossible to say anything bad: beautiful cozy rooms, everything is very clean and comfortable.
The program is quite intensive: we studied both English and French (emphasis was put on French), additional lessons could be chosen - for example, developing speech, thematic (on literature, history, sociology), and all these electives are free. I did not have good command of French for additional classes: for example, for the same sociology, I specified some of the terms from the teacher, because I did not understand them in French. Teachers are very attentive and patient, if you do not understand something, everyone will explain.
The second thing that I remember is a constant fun and activities! I really nearly ran out of space on the phone for photos, we did not miss a minute! Especially I liked to learn water sports: the lake is very close to school, so you can swim, do water skiing or boating, sail. I tried horse riding and archery.
Interesting excursions, we visited beautiful cities and different natural places - Switzerland is really like a picture, in general, never seen anything more beautiful!
Many thanks to SMAPSE for organizing the trip: they chose a school and a program for me, helped me to collect documents. Even during studying in another country I contacted them several times. I recommend the company!
