No topic specific tips, no. Now with multiple choice the examiner has the opportunity to ask questions from the entire syllabus in each exam so question spotting is (as it always was) a waste of time.
The only sensible tip I can give now is that you MUST attempt every question. There is NO set of circumstances that could ever possibly justify a failure to attempt every question.
Spend the rest of today going through a revision kit / exam kit one more time and recheck any topic by looking it up in a study text or on the internet.
