To achieve an 80%+ (first class/high distinction) in law requires you to show independent, critical thinking, near-perfect technical accuracy and advanced research. First things first - you do not only have to summarise the law. Instead, you need to engage in critical evaluation and propose nuanced arguments (where appropriate). Furthermore, use legal databases like Westlaw or LexisNexis to find academic journals and cases beyond the lecture notes. Make sure to develop a clear and consistent ‘guiding thread’ that flows throughout the paper. Also, upon discussing this with an expert law assignment helper, we found that ensuring impeccable referencing (OSCOLO typically) and grammar is a must-do.
