this module is only and only for statistics only. you could change your data to any number (your own calculation) this is just an example that could help you in your upcoming spm. And please note that your real spm result deducts 10 marks based on your work. Do your best, if you're lucky enough, you might get 100% and that is 10 marks for your real result. If you get 90%, therefore you've already got a grip of 9 marks in your real spm result. Do your best! Good luck! xoxo. you can download here ! :)
