ISZL vs. ISOCS vs. Montana

Hi All,

I am moving to Baar in April, we visited a few schools and have shortlisted ISZL (Zug campus), ISOCS in Cham, and Institut Montana.

My son is 7, could anybody please share their experiences? I am more interested in knowing the shortfalls of each of these schools rather than the good things (that was amply covered during the tour).

Any feedback is welcome.

Regards,

F
