Hello this is my first year competing is there any mathematical equations or any equation really that you would recommend I learn in advance.
If possible could you also give the cipher they go with I already know how Index Of coincidence works at a basic level btw.
I recommend reading our codebreaking guide which you can download on the resources page, and then working through Madness’s book which you can get from the BOSS library page. Beyond that I am sure others will have advice – so I will open this discussion to them! Harry
