I foyu didn't use all the licences that came with the software, then just intall and unysed one on your computer. I also think there is a way to transfer a licence from one computer to another, so you can delete the copy that is at school and transfre it to your computer. Look it up first, i'm not sure.
We always intall on our home computers first, cuz they are faster renderers anyway. We also get to tinker in the offseason
