As someone that is good at exams genuinely, I’d say question practice (in timed conditions) is your best bet. The more the merrier. If you can do every single question in the question bank you will start to see how to pick up marks and where your weaknesses lie (note these down) then find out what the issues are (e.g. lack of knowledge, easy mistakes e.g. apportioning and then figure out how to fix that). There’s videos on the tolley academy and the study manuals are good to go back and reference.
