Ability has a good infrastructure. Projectors, wi-fi access, equipped kitchens, computers, etc.…
Close to Federation Square, Flinders Station, tram stops and restaurants it is one of the most well located schools.
I studied the Cambridge Preparation Course, Advanced General English, EAP and IELTS.
A big issue I think exists in this school is the constant exchange of teachers. In my opinion having different accents and methods can be good for learning but I ended up having four different teachers in the same week. This would make it harder for us to engage in class.
Another problem is that there was a big variation in people's abilities in one classroom which made it hard to progress sometimes.
However, those situations mentioned before wouldn't happen in the Cambridge Preparation Course which had well structured content, only two teachers a day (one in the morning and one in the afternoon) and great productivity. I only have two considerations which I made them clear at that time: the exercises we would do in class should be harder (same level of the real test) and there should be an examiner as a teacher but I don't think that is legally allowed.
All in all, I think Ability is a good school and the others might have similar or even the same problems as the turnover of students is huge.
