Hi, I did statistics early last year in year 10 and got an A*. For me, the best way to revise was just going through all the past papers (we did this in class anyway) and remembering all of the equations and how to use them. Also, if you have the CGP revision guide, that can really help. Good luck on your last exam!! Mine was yesterday and it felt sooooooo good to be done!!! You'll do well if you really try!
