GCSE Science Core & Additional

So this guide book is more for my benefit since I have this weird thing where I can memorize stuff more easily from Wattpad than on the computer. I don't know, it may sound weird but I'm just going to see if this could help me for my upcoming GCSE's. This is not supposed to be a story or anything like that; it's just a way for me to study. Any one who stumbles across this are welcome to read and see if it helps them if they are taking their GCSEs this year. Here's praying it will help me.
