Yes. SAS On Demand for Academics is the learning platform for SAS programming. All you need is a PC (Linux, Mac or Windows) and a browser (Chrome preferred).
There are two user interfaces available with SODA. One is SAS Studio, which runs entirely in an internet browser as mentioned by @Kurt_Bremser . The other is SAS Enterprise Guide which must be downloaded and installed on a Windows computer. Back-end processing is entirely online in both cases. The choice is up to you.
