Dear Ramu, you haven't mentioned which law exam you plan on writing. For example if you take CLAT, both Current affairs and General Knowledge section has 50 marks. This is infact the best section to score more. Keep reading the news papers and keep yourself updated with whats happening around the world. The Central Government has come up with lot of developments in the recent times and that is a must read and remember part. Focus on Sports, Science and Technology, History, Arts and Culture sections of the NewsPaper.
