How do stay on topic in the French GCSE 150 word question?

I think the marks on a French 150 word, 32 marker are divided up between3 diff things (could someone clarify what these are pls), one of which is relevancy. I'm really bad at staying on topic/just focussing talking on the one bullet point written down- could someone please give some tips or lmk if they've ran into this problem and what they did to get full marks in the relevancy section?
