You have SW2008. The student editions always have one version of SW and it is always the earlier version.
How it works for the student verions, the first year in the callout dictates the version of SW.
SW Student/Educational 2008-2009 = SW 2008. so SWSE 2009-2010 = SW 2009, 2010-2011 = SW 2010 and so on.
they are always one release back because it's more stable because of service packs and bugs are worked out.
so the bad news is you will have to buy SW Student Edition 2009-2010, $139 12 month license, but only if you are taking 6 or more credits in school.
SW doesn't update the student versions or offer teach support.
