Dear Nafseer,
Last year i.e for 2013, the special supplimentary examination for 4th semester started on 18th February 2013. The notification for this examination was given by the university only during last week of January 2013. So we still have time till January end for this year. Let us hope that our University will give notification atleast during January last week or February first week for S4 special chance. So keep the hopes high, start your preperation now itself and pray to god for our success.
