What are your top briefing tips/tricks?

Always prepare a date chart and summary of arguments / case note. It might seem tedious but it really reduces your work as a briefing counsel. Additionally, whoever is the Senior's associate/junior does not have to read through the entire file at the last moment to assist their Senior after the conference / briefing.

Be thorough with the file. Know where is what document, and what your case is. Be ready as if you have to argue the matter yourself - in the sense that be ready to answer any question that falls from the senior.

Always call the senior counsels junior, and breif/talk with them. Make sure the same person attends every single session.

List of dates is the key.
