Choosing a student care - what's with those worksheets?

Next year, my son needs to go to a student care. I know many people disapprove of it, but I think it is the best option for us. There are many reasons for this choice - both of us are working and we do work late (I finish earliest at 8.30pm and my wife needs to take conference calls at night when projects are due). The only person that can take care of my son is my parents. But they will be unable to help my son much - the syllabus has changed so much from 60 years ago after all. I visited three student care centres around the Marine Parade and East Coast area, checking them out. One of them turned out to be a total disappointment. Despite advertising that they give help based on multiple intelligence, they just do baby-sitting services. They do not even pretend to follow their own marketing! It left two choices. Both seemed to have good administrators and teachers, but one of them really bugged me. They needed us to buy past years examination papers, and the story was that after...
