Throughout my AS level Biology i have endeavored to create a collection of my class notes and revision notes, that i will type up and folder. So i can use them for revision purposes, but then i thought how time consuming this is for me, probably why i didn't think of this sooner!
So i have decided to share all my class notes and revision resources on here for other people studying whom don't have the time to sit and type them all up :)
This Particular one is about the Cardiac cycle and the three stages, i kept it nice and brief for revision purposes.
If you would like anything requested please feel free to comment, i will be adding more and more through out the course.
