I agree with sheewie (interesting name BTW??). I tried migros club schule twice in the first 2 yrs of being here. Can't say either were great experiences unfortunately.
Basically as the others previously mentioned, more down to the teacher (of any subject I would say) than the school. Bear it in mind when you do choose to go to a certain school and ask what the policy is if you aren't finding it "your thing". Suffice to say I pretty much gave up learning german after my 2 experiences...but hey! I'm a defeatist.
Good luck & DONT give up
if it's not for you change.
