Hay Shiva You can instal SAS Studio version you can install it from here https://support.sas.com/documentation/installcenter/ its a lenghty procedure however, if your instructor/teacher has SAS account he/she can give you the domain that would be easy. Regards.
Unless you have lots of money you may want to use the R language instead of SAS which costs big $. R is as good as SAS, but is very different to use. There are lectures on using it on line by Professor Roger Peng and others.
SAS is a commercial statistical product. In my opinion, unless there is a very strong reason for you to use this program, you should move to R, which is fast becoming the most widely used statistical program in academia. This is owing to it being FREE and extremely flexible, as it is open source. Move to R! (as Lewis says, above...)
