The society's president, Michael Gray, said that he anticipated that most students voting in the mock poll would be eligible to take part in the real independence referendum in 2014.
He said: "Quite a large part of the student population are Scottish, with many coming from Glasgow or nearby.
"Other students would be able to register to vote if they were still studying here next autumn.
"There is only quite a small population of Erasmus (European exchange) students who wouldn't be able to vote next year."
The society is also hosting a debate at the GUU featuring Yes Scotland chief executive Blair Jenkins, independent MSP Jean Urquhart, Labour MSP Jackie Baillie, Labour MP William Bain and journalist Lesley Riddoch.
