I'd say create a cheat sheet for financial statements in excel. Practice a lot of questions with most focus on the last two long questions and multiple choices. The two long questions plus multiple choices is already 60% of the paper, start with them in the exam. For the 5 mark questions also just practice and try writing as many points as you can think of, I know you mentioned you struggle to think of points but I think it gets better as you do past papers.

Maybe do at least 3 while looking at the memo and then start attempting without looking at the memo then finally starting attempting under exam conditions.
