I bought and install Solidworks Student Edition for 2012-2013 and the term has expired,Do I have to buy 2013-1014 or can I just renew the period for the 2012-2013 edition.
Welcome to SolidWorks forums Joe.
AFAIK the SolidWorks Student Edition is 12 month term-of-use license and can't be renewed. So you can buy another one year license for 2012-2013 or better go for 2013-2014.

Check with your school to see what version of SolidWorks they are using before you buy a new version.
