Helpful subjects at undergraduate level include Literature, History, Politics, English and Maths along with Public Speaking, Social Studies and a Science in your highschool education. At a postgraduate level, there are few universities who let a non-law graduate or a non-LLB to apply for an LLM course.  However, this depends on the specific university and course you would like to apply for, which Craydel expert admission counsellors can guide you through.
