MATHS CBA 1 HELP/ADVICE

I need help for my maths CBA I'm aiming to get "above expectations" but I'm unsure of what my topic should be and where to start. Some help or advice would be great.

@Emcp Thank you much!! I was just wondering how you collected your data, like what did you ask, I'm sorry if I'm being confusing.

heya, I did redecorating my bedrrom. It was pretty straight forward. Other things you could do would be organize a holiday? One piece of advice would be have as much maths as possible in it becuase the more content the higher your marks

i did mine on building a gym hall for the school it went into alot of depth and it was quite enjoyable
