thanks so much for ur reply..... and what to say , I have my reasons ! !

if a person wants to do an MBA , (my assumption is ) Govt. of pakistan would support him , not only MBA , if sum1 wants to study in any field , the govt. of pakistan will support him financially for his education .... I want to ask , during that period when one is a broad studying , what happens with his seat ?? and is there a limit that you can give these numbers of years to your education during your service and stuff ???

Much obliged !
