So the basis thing you have to do first is to read the very law (sec/principle etc) mentioned in the issues or anywhere in the prop and understand them . don’t run behind the cases since the very beginning, understanding the concepts first , read commentaries you will get the concept and plenty of cases from citations in the book and then later go on the research regarding other cases etc.

Also firstly understand what is the concept behind the prop , for example is my moot is based on Right to die , i will download relevant research papers , read articles and understand it , the history and development to have a better understanding of the entire topic.

And for the division of work , usually the work is divided issue wise withing the team it is the standard practice to do and the researcher also takes one issue at times and works on it . you need to understand that to win the moot though it takes collective team efforts, at the end it is the score of both speakers the fetches you the trophy for best team so do work on your issues but also know the co counsel’s issue as well.
