Edexcel Computer Science Paper 2!!!Watch
i did paper one today too and it went pretty well.anyways for paper two you should probably go over the whole of topic one and two, and learn how to write basic pseudo code:selection iteration etc (flowcharts will come in too but im guessing not as much),and go over some python code so you can understand the code it might ask u about.
go onto page 11 and continue.as long as you can answer each bullet point you'll be fine!
also there are some good videos that cover paper two content on youtube (search computer science tutor, its the one i used for paper one)
