I am a 22 year old girl.....very recently i ped an entrance exam for a course that has a 5 year duration?

and that too in an IIT.........so my question is would it be okk if i join for the course ..and will the age be a problem for my marriage ....because by the time the course gets over i will be in my late 20's. Getting into IIT is such a big thing ,isnt it?
