Should I be worried if I have only studied 1st +2nd year and the Socail change??!!
Just saying, my history teacher says you should avoid social change because it is very hard to get high marks on.
While social change doesn't usually get high marks, you will once you give concise facts. And anyway, it's too late to change now. To be honest, you could get away with not knowing 3rd year history once you know 1st and 2nd year and social change very well.
