Hi I need to know about the getting of computers for the girls. Is there any restriction on the size of the Macbook? Also, do we need to pay for the softwares that the school uses?

Im asking about the computer rgs girls need to get.

I heard that Sapura has only 1 model each. Does that mean theres only 1 size available? May I know what size it is? Also, RGS buys from sapura too right? Means that those who buy through RGS buy from sapura too? I am planning to get an Air, but Im not sure what size i should get and what size is allowed. Sorry for so many questions! Can anyone help answer me?
